New accounts on HN more likely to use em-dashes (marginalia.nu)

Prior to the rise of LLM-written posts and the natural reaction of hair-trigger suspicion, I used to em and en dash fairly often in posts on HN. No reason really other than being a bit of a typography geek who happens to have always used dashes in casual writing instead of semicolons. So when I was setting up a modifier-key keyboard layer with AHK many years ago I put the em dash on modifier+dash just because I could - which made it easy.

Now someone may search old posts without a time cutoff and assume I'm an LLM. That combined with the fact I sometimes write longer posts and naturally default to pretty good punctuation, spelling and grammar, is basically a perfect storm of traits. I've already had posts accused twice in the past year of being an LLM.

Kind of sad some random quirk of LLM training caused a fun little typography thing I did just for myself (assuming no one else would even notice) to become something negative.

My teenager recently asked me why I write like a chatbot, apparently unaware that some human beings prefer to write in complete sentences with attention to details like spelling, punctuation, grammar, and capitalization, and that LLMs were trained on this sort of writing.

This makes me think of the fad where people on youtube will hold a microphone up in frame, because it somehow connotes authenticity. I'm sure some people are already embracing a bit of sloppiness in their writing as a signal of humanity; I'm equally sure that future chatbots will learn to do the same.

I got similar accusations recently on reddit lol. Just because i am used to formatting markdown i like to format some of my reddit comments. i have no idea how to avoid the accusations besides typing less formally except by typing like thisss.

I started making deliberate grammar and spelling mistakes in professional context. Not like I have a perfect writing anyway, but at least I could prove that it was self-written, not an auto-generated slop. (Could be self-written slop though :)

This applies not only work-stuff itself also to the job-applications/cv/resume and cover-letters.

You're absolutely right! I kid. I'm also a former avid user of the em-dash, but have mostly stopped using it. I've even started replacing em-dash usage with commas, which often results in a slightly awkward, perhaps incorrect, but quaintly artisanal sentence with a LaCroix-like spritz of authenticity.

My double-space-after-a-period though, I will keep that until the end. Even if it often doesn't even render in HTML output, I feel a nostalgic connection to my 1993 high school typing teacher's insistence that a sentence must be allowed to breathe.

Hell I've been accused simply for using markdown. Granted, excessive formatting in markdown (especially when I'm telling a bad faith wikipedia contributor to cut it out since wikipedia doesn't even use markdown) is one of the biggest suspects for me but theres a difference between italicising something for emphasis and and *bolding* every statement *to an excessive degree*

For those who are interested, that one is Alt-7 (numeric keypad) on Windows. This works because in the "OEM" codepage (e.g. 437), char 7 corresponds to a symbol that is mapped into Unicode to • (← I just typed this using Alt-7, and the arrow using Alt-27). In a similar way I type the infamous ones—the ones that give you away as an LLM even if you aren't one. It's Alt-0151, this time with no OEM codepage conversion because of the zero in front (anyway that codepage had no em-dashes, the closest one would be Alt-196, which is ─, i.e. a line drawing character).

Ex-academic here. I too use/tended to use em-dashes quite a bit. It's easy to compose in Linux (Gnome) with a real keyboard: Ctrl Shift U 2014 is ingrained in my head from using them all the time in my academic work.

Were you using them as a replacement for a comma--without spaces on both sides of the em-dash--like how I did just now? If no, you are safe from being mistaken for an LLM program. Honestly, while it is a legitimate punctuation rule, I've never seen a human on the internet to write like that. But LLMs do it constantly, whenever they generate long enough sentences.

I'm a human who writes like that, because mobile and desktop OSs have made it easy—so easy—to include things like em-dashes and other formerly uncommon punctuation. I also come from an age where people were taught things like proper grammar and punctuation, so go figure.

Sadly, I think the same is true for my two posts accused of being LLM generated. It's become a bit of a reflexive witch-hunt when just being more than five sentences and basically decent grammar / vocabulary is enough to garner some drive-by accusations. Hopefully, it's a short-term over reaction that will subside.

I'm also increasingly aware that my own writing style and punctuation seem to line up with what might be associated with an AI, but some of the tells (em-dashes, spaces after periods, etc) seem like artifacts of when in history we learned to write.

I wonder how much crossover there would be between a trained text analysis model looking for Gen-X authors and another looking for LLM's.

I worked on something like this in 2000-1.

Well, to be fair Gen-z slangs also have a massive impact. My generation sometimes point blank said to me that they didn't have the attention span to read my sentence :/

Definitely picked up a few slangs along the way now. I had to somehow toggle a switch between how I write on HN/how I write with my friends the first few times and I write pretty informally in HN, but its that you got to be saying lowk bussin rizz 67 to make sense.

My friends who use insta literally had Abbreivations which were of 9 letter words in my own language that the insta community of my nation's gen-z sort of made.

Although I would agree that we haven't seen a whole unicode being thrown this way in ALL generations (I feel like universally everyone treats em-dashes as something written by AI or definitely get an AI alert)

But I think that 67 is something that atp maybe even most adults might have gotten exposed to which has probably changed the meaning of number.

I used to do that too… even using the ellipses character instead of three dots. But on the other hand I'm not a native English speaker and have poor spelling (i.e. words pass spell check, but are incorrect).

That's one of the signals I use to detect if YouTube videos are AI slop. If it's narrated by a non-native speaker, it's much more likely to be high quality. If it's narrated by a British voice with a deep timber, it's 100% AI.

Worth pointing out that calculating p-values on a wide set of metrics and selecting for those under $threshold (called p-hacking) is not statistically sound - who cares, we are not an academic journal, but a pill of knowledge.

The idea is, since data has a ~1/20 chance of having a p < 0.05, you are bound to get false positives. In academia it's definitely not something you'd do, but I think here it's fine.

@OP have you considered calculating Cohen's effect size? p only tells us that, given the magnitude of the differences and the number of samples, we are "pretty sure" the difference is real. Cohen's `d` tells us how big the difference is on a "standard" scale.

It's funny - some months ago I noticed that I use the word "actually" lot, and started trying to curb it from my writing. Not for any AI-related reason, but because it is almost always a meaningless filler word, and I find that being concise helps get my points across more clearly.

e.g. "The body of the template is parsed, but not actually type-checked until the template is used." -> "but not typechecked until the template is used." The word "actually" here has a pleasant academic tone, but adds no meaning.

steve_adams_86 4 hours ago

I try to curb my usage of 'actually' too. Like you I came to think of it as an indirect, fluffy discourse marker that should be replaced with more direct language.

I'm totally fine with the word itself, but not with overuse of it or placing it where it clearly doesn't belong. And I did that a lot, I think. I suspect if you reviewed my HN comments, it's littered with 'actually' a ton. Also "I think...", "I feel like..." and other kind of... Passive, redundant, unnecessary noise.

Like, no kidding I think the thing I'm expressing. Why state that?

Another problem with "actually" is that it can seem condescending or unnecessarily contradictory. While I'm often trying to fluff up prose to soften disagreement (not a great habit), I'm inadvertently making it seem more off-putting than direct yet kind statements would. It can seem to attempt to shift authority to the speaker, if somewhat implicitly. Rather than stating that you disagree along with what you believe or adding information to discourse, you're suggesting that what you're saying somehow deviates from what the person you're speaking to would otherwise believe or expect. That's kind of weird to do, in my opinion. I'm very guilty of it, though I never had the intent of coming across this way.

It can also seem kind of re-directive or evasive at times, like you don't want to get to the point, or you want to avoid the cost of disagreement. It's often used to hedge statements that shouldn't be hedged. This is mainly what led me to realize I should use it less. I hedge just about everything I say rather than simply state it and own it. When you're a hedger and you embed the odd 'actually' in there, you get a weird mix of evasive or contradictory hedging going on. That's poor and indirect communication.

Actually, this specific example usage of "actually" could have a meaning. It depends.

"The body of the template is parsed, but, contrary to popular belief, not actually type-checked until the template is used."

One can omit the "contrary to popular belief", but the "actually" would still need to stay, as it hints at the "contrary to popular belief".

It's not as simple as "it's not needed there".

The lack of recognition of perceived Noise as an actual part of the Signal, eventually destroys the Signal.

Such data analysis of HN related things are always so fun to read. Thanks for making this!

I have a quick question but can you please tell me by what's the age of "new" accounts in your analysis?

Because, I have been called AI sometimes and that's because of the "age" of my comments sometimes (and I reasonably crash afterwards) but for context, I joined in 2024.

It's 2026 now, Almost gonna be 2 years. So would my account be considered new within your data or not?

Another minor point but "actually"/"real" seems to me have risen in usage over 5 times. All of these words look like the words which would be used to defend AI, I am almost certain that I saw the sentence "Actually, AI hype is real and so on.." definitely once, maybe even more than once.

Now for the word real, I can't say this for certain and please take it with a grain of salt but we gen-z love saying this and I am certain that I have seen comments on reddit which just say "real" and OpenAI/other models definitely treat reddit-data as some sort of gold for what its worth so much so that they have special arrangements with reddit.

So to me, it seems that the data has been poised with "real". I haven't really observed this phenomenon but I will try to take a close look if chatgpt is more likely to say "real" or not.

Fwiw, I asked Chatgpt to "defend the position, AI hype sucks" and it responded with the word "real"/"reality" in total 3 times.

(another side fact but real is so used in Gen-z I personally watch channel shorts sometimes https://www.youtube.com/@litteralyme0/shorts which has thousands of videos atp whose title is only "real", this channel is sort of meme of "ryan gosling literally me" and has its own niche lore with metroman lol)

LLM fatigue is real. It's not just em-dash — it's the overall tone of the writing that clues people in. But if your viewpoints and approach are unique, your typesetting won't raise suspicion of machine-generation, except in the most dull of readers. Just be you and it will be fine.

Magical signal panacea searching is ultimately fruitless. Other ways to make bot interactions more difficult, there are policy and technological obstacles that could be introduced. For example, require an official desktop or mobile app for interaction. And then for any text copy-pasted, demarcate it. And throw an error message for any input typed inhumanly-fast. Require a micropayment of like $0.10 to comment. While these things would break the interaction style and flexibility for a lot of innocent human users, these would throw big wrenches into some but not all vulnerabilities of bot interactions.

In a lot of ways, it feels like this is simply a fight for recognition that the Mac keyboard supports emdashes.

This wouldn't be an issue if mobile users or Windows users were exercising it too, but it's just Mac owners and LLMs. And Mac owners are probably the minority of instances where it is used.

There are times when an em dash can be used in place of a semicolon, but I don't think that's the usual LLM usage. Instead it's replacing a replacing a comma, colon, or period.

Unless you're talking about restructuring your sentences to allow for a semicolon; that's fine.

For example that semicolon could have been an em dash, but I don't think it's the type that LLMs over favor.

embedding-shape 5 hours ago

People will accuse of all types of stuff, regardless if you use em-dashes or not. The way I write apparently is familiar to some as LLM-jargon they've told me, I'm guessing because I've spewed my views and writings on the internet for decades, the LLMs were trained on the way I write, so actually the LLMs are copying me! And others like me.

But anyways, you can't really control how people see your stuff, if you're human I think the humanness will come through anyways, even if you have some particular structure or happen to use em-dashes sometimes.

Funnily enough I've actually started using them a little — it made me realise how much more legible/likable I find them.

I mean, LLMs aren’t making people sniff around for typography as though that’s a reliable proxy for humanity.

Em dashes, semicolons, deftly delving. It’s all just so…facile. We might as well tell ourselves we can tell it’s shopped from the pixels, having seen some shops in our day.

I feel the same way. I've used em-dashes in my writing forever, and I was always particular about making sure they were used properly (from a typography standpoint with no surrounding spaces).

But now, I have to be so picky about when I use them, even when I think it's the perfect punctuation mark. I'll often just resort to a single hyphen with spaces around. It's wrong, but it doesn't signal someone to go "AI AI AI!!"

The issue is that LLMs adopt a very particular style that is a mix of being very polished (em-dash, lists-of-three, etc) that is reminiscent of marketing copy, and some quirks picked up from the humans curating the training data somewhere in Africa

If AI was writing like everyone else we wouldn't be talking about this. But instead it writes like a subset of people write, many of them just some of the time as a conscious effort. An effort that now makes what they write look like lower quality

This feels like an existential threat to HN, and to the general concept of anonymous online discourse. Trust in the platform is foundational, and without it the whole thing falls down.

Requiring proof of identity is the only solution I can think of, despite how unappealing it is. And even then, you'll still have people handing their account over to an LLM.

I really struggle to imagine a way around it. It could be that the future is just smaller, closed groups of people you know or know indirectly.

kanzure an hour ago

Another option instead of using identity is to use proof of work or hashcash such that anyone who thinks a comment is valuable can use some hash rate to upvote it. It doesn't matter how the content was generated, only that someone thought it was important, and you can independently verify this by checking how much hash effort went into hashing for that comment. This also does not require any identity either.

I don't think that's true at all.

One of the things HN does is not let you interact in certain ways until you've earned sufficient karma. This is a basic proof-of-work. If your bot can't average a positive karma, then it'll never get certain privileges.

Not to say the system is perfectly tuned for bots, because it's not. The point is that proof of identity is not the only option.

rob 14 minutes ago

They get the privilege of immediately polluting the website with LLM-generated comments.

Many of them sound and look completely normal and have others on here interacting with them. They don't use em dashes, sometimes they'll use all lowercase text, sometimes the owner of the bot will come out and start commenting to throw you off.

All examples I've witnessed here.

HN should immediately start implementing at least some basic bot detection methods without requiring us to email them every time. I've discovered multiple bots make detailed comments within 30 seconds of each other in different threads, something a normal human wouldn't be able to do. That should be at least flagging the account for review. Obviously they'll get smarter and not do that soon but it would help in the short term.

I'd say it's not an issue but everything I described above has happened in less than a month and every day now I'm discovering bots here.

3rodents 2 hours ago

HN is almost entirely about the comments. Voting is useful as a tool for loosely sorting content but otherwise, HN could easily do without it. Some of the most valuable comments come from people with barely any karma. And that’s why HN is great! The restrictions on voting and flagging for new users could be removed without impacting the quality of HN. I can’t imagine any scenario in which HN’s current system could survive the same slopification that is happening on reddit.

HN is doing okay at the moment because nobody is yet publishing ebooks and videos on how to astroturf HN to launch your SaaS. Unfortunately, Reddit hasn’t escaped that fate.

One pattern I've noticed recently is sort of formulaic comments that look okish on their own, maybe a bit abstract/vague/bland, and not taking a particular side on good/bad in the way people like to do, but really obviously AI when you look at the account history and they're all the same formula:

>this is [summary]

>not just x, it's y

>punchy ending, maybe question

Once you know it's AI it's very obvious they told it to use normal dashes instead of em dashes, type in lowercase, etc., but it's still weirdly formal and formulaic.

For example from https://news.ycombinator.com/threads?id=snowhale

"this is the underreported second-order risk. Micron, Samsung, SK Hynix all allocated HBM capacity based on hyperscaler capex projections. NAND fabs are similarly committed. a 57% reduction in projected OpenAI spend (.4T -> B) doesn't just affect NVIDIA orders -- it ripples into the memory suppliers who shifted capacity to HBM and away from commodity DRAM/NAND. if multiple hyperscalers revise down simultaneously you get a situation similar to the 2019 crypto ASIC overhang: companies tooled up for demand that evaporated. not predicting that, but the purchasing commitments question is real."

The user [1] you've mentioned has 160 points being a poster of total four bland messages. This goes against a normal statistical distribution.

AI generated content routinely takes sides. Their pretense of neutrality is no deeper than a typical homo sapien's. This is necessarily so in an entity that derives its values from a set of weights that distill human values. Maybe reasoning AI can overcome that some day, but to me that sounds like an enormous problem that may never be solved. If AI doesn't take sides like people do they still take sides in their own way. That only becomes obscure to the extent that their value judgments conflict with ours, and they are very good at aligning with the zeitgeist values, so can hide their biases better than we can.

I wonder if it is neural networks that are inherently biased, but in blind spots, and that applies to both natural and artificial ones. It may be that to approximate neutrality we or our machines have to leave behind the form of intelligence that depends on intrinsically biased weights and instead depend on logically deriving all values from first principles. I have low confidence that AI's can accomplish that any time soon, and zero confidence that natural intelligence can. And it's difficult to see how first principles regarding human values can be neutral.

I'm also skeptical that succeeding at becoming unbiased is a solution, and that while neutrality may be an epistemic advance, it also degrades social cohesion, and that neutrality looks like rationality, but bias may be Chesterson's Fence and we should be very careful about tearing it down. Maybe it's a blessing that we can't.

I went through a phase where I milled responses through grinding plates of LLMs. Whether my reasons are shared with others remains unknown.

My relationship with writing, while improved, has been a difficult one. Part of me has always felt that there was a gap in my writing education. The choices other writers seem to make intuitively - sentence structure, word choice, and expression of ideas - do not come naturally to me. It feels like everyone else received the instructions and I missed that lesson.

The result was a sense of unequal skill. Not because my ideas are any less deserving, but because my ability to articulate them doesn't do them justice. The conceit is that, "If I was able to write better, more people would agree with me." It's entirely based on ego and fear of rejection.

Eventually, I learned that no matter how polished my writing is, even restructured by LLMs, it won't give me what I craved. At that moment, the separation of writer and words widened to a point where it wasn't about me anymore and more about them, the readers. This distance made all the difference and now I write with my own voice however awkward that may be.

I was going to say that I respect it, but find it utterly absurd that they do that. But your comment made me look it up again—I had no idea it was just obsolete/archaïc (except in the New Yorker), I'd thought it was a language feature their 'style' guide had invented.

Aachen 3 hours ago

Dutch does this. Idea is idee, with the e doubled to show it's a long vowel. We make plurals by adding "en". One idee, two... ideeen? Idewhat? So the dots differentiate where the sound changes (long e to short e): ideeën. Approximate pronunciation could be "ID an"

Fun fact: if you have the audacity to correctly write an SMS, you can fit about 70 characters in an SMS. It converts the whole message into multibyte instead of only adding dots to the one character. Or if you use classic spelling for naïve in English, same issue. (We don't dots-ize that in Dutch because ai is not a single sound like ee is, so there's no confusion possible. This is purely English.) I believe in Hanlon's razor so it's probably a coincidence that whoever cooked up this terrible encoding scheme made carriers a lot of money, but I do wonder if this had anything to do with the bug still existing to this day!

While someone who doesn't like AI slop and knows and what to look out for will notice and call out obvious AI comments, the unfortunate truth is that the majority of people simply cannot tell, and even among those who can, many don't care.

Obvious AI-generated posts and articles make it to the front page on a daily basis, and I get the impression that neither the average user nor the moderation team see that as a problem at all anymore.

If I see an em-dash in a comment I stop reading and I've seriously considered setting up a filter across multiple sites to remove any comments containing one.

I know there are legitimate usecases for the em-dash, but a few paragraphs (at most) of text in an HN/Reddit comment? Into the trash it goes.

This is probably the time to add some invitation system like GMail had in the beginning. Or make a shade for accounts <1yr. Or something else, before things get too mixed.

shit_game 6 hours ago

The issue with creating some hidden maturity heuristic for accounts is that it will be gamed just the same as any other, except that using age alone is the simplest heuristic to game. You can simply do nothing for incrimental periods of time and then begin testing aged accounts to roughly determine what the minimum age an account must reach to become "trusted".

Bot prevention is a very difficult constant game of cat and mouse, and a lot of bot operators have become very skilled at determining the hidden metrics used by platforms to bless accounts; that's their job, after all. I've become a big fan of lobste.rs' invitation tree approach, where the reputation of new accounts rides on the reputation of older accounts, and risks consequence up the chain. It also creates a very useful graph of account origin, allowing for scorched earth approaches to moderation that would otherwise require a serious (and often one-off) machine learning approach to connect accounts.

I wanted to point out that em dashes are autocompleted by the iOS keyboard. So the false positives and true negatives might have some overlaps without more details. I think a better indicator would be to only detect em dashes with preceding and following whitespace characters, and general unicode usage of that user.

Additionally, lots of Chinese and Russian keyboard tools use the em dash as well, when they're switching to the alternative (en-US) layout overlay.

There's also the Chinese idiom symbol in UTF8 which gets used as a dot by those users a lot, so that could be a nice indicator for legit human users.

AI post "improvements" are the most annoying thing. I see more and more people doing it, especially when posting reviews/experiences with things, and they always get called out for it. They always justify it with "AI helped me organize what I wanted to say." Like man, you're having an AI write about an experience it didn't have and likely didn't even proofread it. Who knows what BS it added to the story. Even disorganized and misspelled stories are better than AI fantasy renditions that are 20 times longer than they need to be.

If you are suspicious, look at comment history. It's usually fairly obvious because all comments made by LLM spambots look the same, have very similar structure and length. Skim ten of them and it becomes pretty clear if the account is genuine.

I'm more worried about how many people reply to slop and start arguing with it (usually receiving no replies — the slop machine goes to the next thread instead) when they should be flagging and reporting it; this has changed in the last few months.

If you are suspicious, look at comment history.

I'm never suspicious though. One of the strange, and awesome, and incredibly rare things about HN is that I put basically zero stock in who wrote a comment. It's such a minimal part of the UI that it entirely passes me by most of the time. I love that about this site. I don't think I'm particularly unusual in that either; when someone shared a link about the top commenters recently there were quite a few comments about how people don't notice or how they don't recognize the people in the top ranks.

The consequence of this is that a bot could merrily post on here and I'd be absolutely fine not knowing or caring if it was a bot or not. I can judge the content of what the bot is posting and upvote/downvote accordingly. That, in my opinion, is exactly how the internet should work - judge the content of the post, not the character of the poster. If someone posts things I find insightful, interesting, or funny I'll upvote them. It has exactly zero value apart from maybe a little dopamine for a human, and actually zero for a robot, but it makes me feel nice about myself that I showed appreciation.

I was thinking of how to create a UX around quantifying or qualifying AI use. If products revealed that users had used in-app AI to compose their responses, they might respond by doing it outside the app and pasting it in. If you then labeled pasted text as AI they might use tools to imitate typing. And after all that, you might face a user backlash from the users who rely on AI to write.

You can turn off iOS automatically converting dashes to em-dashes.

Several factors: 1. Em dashes are common use in the Queens English

2. People with dyslexia and dysgraphia can more easily interact online

3. People who speak a primary language other than English can more easily interact online

The last 2 options mean people who previously would have been more reluctant to participate now have less of a barrier.

So while there may be AI generated content, we should just assume it is all negative.

Our life has become so dumb in certain ways. There are people who invested heavily in learning their mother or a foreign language, its spelling, grammar, syntax and idiosyncrasies, like when to use an em-dash, an Oxford comma, a semicolon, an ellipsis -- these smart educated people now seriously deliberate whether using wrong dashes and adding a spelling mistake or two would be a good way to prove you are a human (I think we never should have allowed the framing of CAPTCHA to be "prove you are not a robot", it was demeaning back then and still is now, it's just that the alternatives were not and still aren't clear-cut). The same things that would have made you fail a written essay in school are somehow becoming a requirement, but not in "haX0r" or online communities where "writing funny" has always been a differentiating factor, but for absolutely everybody who has to communicate with others in written form.

It's of course not a surprise that an LLM would be most proficient in language use and, adjacent to that, in proper formatting of said language. But it's a good thing and a good tool for writing, as anyone who has ever used a classic spell or grammar checker will attest to. But apparently we as a society have once again managed to completely overlook and demonise the good and now people who have paid attention in school have to bow to people who are somehow convinced that perfect spelling is a sign that someone cheated. This is not LLMs' fault, it's people's who think they've understood something when they really haven't, crying heresy over others doing things the correct way.

That being said: of course there are social and technological challenges with cheating, spam bots and sock puppets and what not, but the phenomenon itself is not really new, just the scale, cost and quality is way different now. We need to find a balanced way to approach it -- trying to weed out every last possible AI cheater while hurting real innocent people in the process is not worth it. Especially since we don't have a proper metric to actually prove who's a cheater and who is not, it's gotten way harder since the days of "As a large language model" being in every second sentence.

I felt it quite a while back (more than 10 years ago), when, in high school, I learnt LaTeX and discovered Beamer. I naturally proceeded to make all of my presentations with it, including the rehearsal for a big competitive French exam. The person reviewing the presentation advised me to dirty it up a bit, otherwise nobody would believe that my father wasn’t a PhD researcher that did the work for me.

That was a bit saddening honestly. I kept the presentation as-is as I didn’t knew how to willfully screw up a Beamer presentation, and I would not touch PowerPoint (fortunately the final jury believed me).

Cheating had always been an issue before LLMs, but now we’re back to the same old tricks: just make sure to add a mistake or two to hide you copied the homework on your neighbor. It’s a shame because I kinda like learning the subtleties of foreign languages, and as a non-native English speaker, it’s quite rewarding when going online!

I know on reddit since basically the very beginning there has been a market for accounts with authentic but anodyne histories. It ends up being easier to make them yourself and then just occasionally use them for whatever guerilla marketing, astroturf campaign, or propaganda operation is your actual goal. But still until recently you pretty much had to pay people to sit and post on social media on a bunch of accounts to generate these histories.

This use was one of the first things that occurred to me when LLMs started getting genuinely good at summarizing texts and conversations. And I assume a fair bit of this has always happened on HN too. I've never moderated here obviously so I have no first hand insight but the social conventions here are uniquely ripe for it and it has a disproportionate influence on society through the dominance of the tech industry, making it a good target.

Getting stories on the front page of HN can get them spread across the entire media. Also, you end up with a bunch of accounts that can upvote comments/posts that you're pushing and downvote/flag the ones that criticize them.

Lots of dumb blogs from unknowns about vibecoding entire products in a weekend using specific AI slop generators from new startups that are getting to the front page lately.

remember: 1) those accounts that are causing 10x as many em-dashes are the dumb AI accounts. The smart ones are at the least filtering obvious tells from the output. They might even outnumber the dumb ones.

2) Also, a lot of people are real, but using AI to make themselves sound smarter. It's not necessarily completely nefarious.

Using em-dashes as an estimate has to result in a bunch of undercounting and overcounting.

This `-` is a hyphen, which I love, even if I'm fairly sure I'm not using it correctly in grammar a lot of the time.

This `--` is an EM-Dash, apparently, which is also what I never use but I also thought was just a hyphen in a different context (incorrect!).

As a typography nerd, I’m upset that my pedantism may get me labelled as a bot. (Yes, I just used a typographic apostrophe instead of a straight single quote.)

fuzzy2 6 hours ago

Yeah, same. I use an extended keyboard layout on my PC. I'm so used to it I have to actively decide against using proper quotes and dashes and whatnot. I don't bother on mobile, though.

Every time someone states they stop reading when they encounter proper typography, I feel attacked.

Poor poor those typography-savvy people who did set a special keyboard in order to type "proper" dashes. I know you are there, I know your pain.

No fancy keyboard required, just a keystroke on Mac (`alt+shift+-`) and Linux (`right alt+something` depending on your distro).

I learned just right now that this isn't the default. I set my bookmark to HN in like 2011 before making an account, and apparently it's that one. I didn't realize that wasn't just the basic homepage but with a weird address for some reason.

like bang instead of exclamation point? or dot instead of period? I like it.

even though I used to like pointing out the difference between a hyphen and a period.

Rooster61 6 hours ago

It makes it much more fun to imagine a room full of robots in overcoats trying to pass off as human, but doing a terrible job due to the audible "clanks" betraying them from beneath the coat.

Spaces like HN then become a cacophony of clankers clanking as their numbers increase

Not everyone speaks English natively—most have relied on Google Translate in the past, and now they turn to AI tools. There's nothing wrong with that, provided they're using these tools to express their own thoughts rather than for spam or botting.

If you control a bunch of established accounts, you can use them to either shill for products, or upvote certain topics.

- Spam a product/service

- Generate age so spamming a product/service is easier and the account appears more trustworthy

- Influence discussions in a particular direction for monetary gain, i.e. "I got rich on bitcoin, you'd be crazy not to invest".

- Influence discussions in a particular direction for political gain, i.e. "I went to Xinjiang and the Uyghurs couldn't be happier!"

TBH, I learned about how to use em dashes from the AI controversy and now I find them really useful.

I just hope my writing carries enough voice and perspective that people respond, even if there's an em dash or two.

It has been obvious since ChatGPT that the internet, including HN, will be flooded with AI generated commentary, drowning out real peoples' voices (soon undetectable). How this is surprising to anyone is a mystery.

The fear is that AI-generated comments will collectively promote an agenda, often a political or exploitative agenda, on a scale that humans can't match or hope to counter.

What could help is a careful clique hunting algorithm to accurately identify and delete the entire clique.

Paid actors, regular people and primitive bots are already doing so plentifully and successfully.

Of course, all of the above can be replaced by AI, but it would not significantly alter the status quo.

Karma aside, flooding the comments with a chosen narrative via army of bots seems like it's already happening. I suppose the bots can also do voting rings, but they don't necessarily need to.

Would be interesting to see "fastest growing accounts in last N months" or something similar. I'm guessing the ones that are actually humans would be closer to the top than the bottom, but maybe HN users aren't better than the average person to detect AI or not.

It can crank proof of work schemes to maximum, something like you need to burn 15-20 minutes 16 core cpu to post a single comment. It will be infuriating for users, but not cheap for bots

One solution is to get rid of anonymity online, enforce validation of identity. Every human only gets 1 account. And then we still ban people that use AI. Might take a bit but eventually we'll have filtered out all the grifters.

If that's worth the cost... probably not?

OutOfHere 6 hours ago

Getting rid of anonymity is in time going to lead to getting rid of the platform, so do it if you're feeling suicidal. People seek real anonymity for good reason. Not everything should follow them in life or for life.

Something about correlation and causation of magic gotcha signals. Text may appear generated to a reader but there's no smoking gun evidence that can disambiguate fact from hypothesis. Even intuition isn't evidence.

Perhaps there needs to be some sort of voluntary ethical disclosure practice to disclaim text as AI-generated with some sort of unusual signifiers. „Lower double quotes perhaps?„

Maybe the em dash is the self censorship/deletion mechanism that we've all been waiting for. Better than having to write pill subscription ads, I suppose.
