Plenty of people, especially new HN users, think that Markdown works on HN, I don't think it automatically means they're AI.
However, if they don't update the comment, I'd also put another point towards "Could be AI" as you get shown your comment immediately after.
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.
Is it possible to differentiate between a bot, and a human using AI to 'improve' the quality of their comment where some of the content might be AI written but not all? I don't think it is.
hm, the whole internet really, youtube, reddit, twitter, facebook, blog posts, food recipes, news articles, it's getting more and more obvious

Could be an argument made for aggregating by user instead however, if some bots are found to be particularly active and skewing the data.
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.
What will/can HN do about it?
(1) I don't recommend focusing disproportionately on one signal. They'll change, and are incredibly easy to optimize for. https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing
(2) I do recommend taking one minute to dash a note off to hn@ycombinator.com if you see suspicious patterns. Dang and our other intrepid mods are preturnatually responsive, and appear to appreciate the extra eyeballs on the problem.
