I do not have anything specific. I have read threads where someone, usually with snark, responds with a comment of the sort "are you a bot?", or "you sound like chatGPT". That's probably only been a couple times over a few months, and I'm on HN reading threads multiple times a day, so it's not very frequent. But it does make me wonder... That distinctive ChatGPT style will become less recognizable. IMHO, bot content in the HN comments should be fairly low, but non-zero. I don't think there's much, if any, incentive to invest much in an HN comment bot, but with all these hackers/coders some would do it just out of curiosity/challenge.
