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 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.

> I started making deliberate grammar and spelling mistakes in professional context.I've also noticed an increase of this in myself and others, I used to edit a lot more before sending anything, but now it seems more authentic if you just hit send so it's more off the cuff with typos, broken sentences and all.
I'm sure an LLM could easily mimic this but it's not their default.

unrelated but I've never understood how to put a smiley at the end of parenthetical sentences (which comes up surprisingly often for me since I use smileys a lot and also like using parentheses). Just the smiley as an end parentheses (like this :) feels off but adding another parentheses (like this :) ) makes it look like it should be nested which causes problems since I also tend to nest parenthetical sentences (like (this)).Yes I enjoy lisp, how could you tell

The answer is obviously to balance your smiley faces and wrap the entire statement in the smiley face sentiment. ((: Like this :))by sevensor

I like this simply for the absurdity of it, but will only use it when the entire parenthetical is modified by the smiley instead of a single word or phrase (:since I really like it:) but (it looks ugly, no hard feelings :) )by mghackerlady
2/25/2026 at 8:44:05 PM
Your comment made me realise that there's logic to this (like this :), since in HTML we can: <li> do this

instead of: <li> ... </li>and <img alt='this'> instead of <img ... />

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.
by jeremy151
2/25/2026 at 10:25:40 PM
I use double hyphens instead of em-dashes when I'm on my computer. I think some programs will combine them into an em-dash but most of the time they're just double dashes.My phone lets me long-press the hyphen key to get an em-dash so sometimes I'll use it.
Probably the biggest tell that I'm not AI is that I'm probably not using it in the appropriate circumstances!

Hell I've been accused simply for using markdown.

2/25/2026 at 8:27:54 PM
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).by ale42

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.by Yizahi
2/25/2026 at 10:04:55 PM

soon were gonna be the ones adding random typos and grammer errors just to blend in. i skip apostrophes and mispell words on purpose already. its strange how fast sloppy writing starts feeling natural(This above line itself was written by AI itself: https://www.kimi.com/share/19c96516-4032-8b73-8000-0000f45eb...)
I don't know if worse grammar could make a difference aside from removing false negatives (ie. nowadays people with good grammar are questioned if they are LLM's or not) but this itself doesn't mean that worse grammar itself means its written by a human. (This paragraph is written by me, a human, Hi :D)
by Imustaskforhelp
2/25/2026 at 7:54:57 PM
Honestly, first paragraph sounds more human and sincere for sure.Also adding better "context" into the discussion, than the usual claims/punchlines of marketing-speak.
Maybe it's not exactly the grammar itself but also overall structuring of the idea/thought into the process. The regular output sounds much more like marketing-piece or news-coverage than an individual anyway. I think, people wanna discuss things with people, not with a news-editor.
by pvtmert
2/25/2026 at 8:43:00 PM
> I think, people wanna discuss things with people, not with a news-editor.If I understand you correctly, then Yes I completely agree, but my worry is that this can also be "emulated" as shown by my comment by Models already available to us. My question is, technically there's nothing to stop new accounts from using say Kimi and to have a system prompt meant to not sound AI and I feel like it can be effective.
If that's the case, doesn't that raise the question of what we can detect as AI or not (which was my point), the grand parent comment suggests that they use intentionally bad human writing sometimes to not be detected as AI but what I am saying is that AI can do that thing too, so is intentionally bad writing itself a good indicator of being human?
And a bigger question is if bad writing isn't an indicator, then what is?
Or if there can even be an good indicator (if say the bot is cautious)? If there isn't, can we be sure if the comments we read are AI or not
Essentially the dead-internet-theory. I feel like most websites have bots but we know that they are bots and they still don't care but we are also in this misguided trust that if we see some comments which don't feel like obvious bots, then they must be humans.
My question is, what if that can be wrong? It feels to me definitely possible with current Tech/Models like say Kimi for example, Doesn't this lead to some big trust issues within the fabric of internet itself?
Personally, I don't feel like the whole website's AI but there are chances of some sneaky action happening at distance type of new accounts for sure which can be LLM's and we can be none the wiser.
All the same time that real accounts are gonna get questioned if they are LLM or not if they are new (my account is almost 2 years old fwiw and I got questioned by people esentially if this account is AI or not)
But what this does do however, is make people definitely lose a bit of trust between each other and definitely a little cautious towards each message that they read.
(This comment's a little too conspiratorial for my liking but I can't help but shake this feeling sometimes)
It just is all so weird for me sometimes, Idk but I guess that there's still an intuition between whose human and not and actually the HN link/article iteslf shows that most people who deploy AI on HN in newer accounts use standard models without much care which is the reason why em-dashes get detected and maybe are good detector for sometime/some-people and this could make the original OP's comment of intentionally having bad grammar to sound more human make sense too because em-dashes do have more probability of sounding AI than not :/
It's just this very weird situation and I am not sure how to explain where depending on from whatever situation you look at, you can be right.
You can try to hurt your grammar to sound more human and that would still be right
and you can try to be the way you are because you think that models can already have intentionally bad grammar too/capable of it and to have bad grammar isn't a benchmark itself for AI/not so you are gonna keep using good grammar and you are gonna be right too.
It's sort of like a paradox and I don't have any answers :/ Perhaps my suggestion right now feels to me to not overthink about it.
Because if both situations are right, then do whatever imo. Just be human yourself and then you can back down this statement with well truth that you are human even if you get called AI.
So I guess, TLDR: Speak good grammar or not intentionally, just write human and that's enough or that should be enough I guess.

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.

This isn't even really limited to just the em-dash, but I don't know if there's another example of a corporation (or set of them) having such a massive impact on grammar and writing as OpenAI and their ilk have.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.
