You can't. Either people will say you're overreacting to stylistic choices and that it's not AI, or that it's AI but a good comment (it's not), or that it's AI and a bad comment, but you should just ignore it like any other spam.

For now, a js script that hides green username comments

It’s horrible. I got chewed up here for a similar reason… noting suspicious comments (same top level thread as this one): https://news.ycombinator.com/item?id=47115805

Wouldn't it be ironic if LLMs are what saves us all from our digital addictions? There's not much point in shit posting online if there's no confidence that the person you're talking to is even a person.

I mean over time I'd imagine they'll be able to tune away from the 'LLM style' chat making it even more ambiguous who is human and who is not, and at which point, I expect many of us might be forced to accept what a waste of time this all is, all the while bots 'chat' with one another.

This website is under attack from relentless AI slop spam, both in submissions and in comments, and I have absolutely no idea what we can do about it. To me this stuff is an existential threat to a site like this.

I moderate a mid sized subreddit (few hundred thousand) and I ban AI spammers on sight with extreme prejudice, but I don't feel like that same attitude meshes well with HN.

Flag them without pity, and block green usernames.
