I wish all platforms did this specially reddit, twitter etc. I don't use AI to write comments on any platform and always wondering if I am replying to an AI comment.
Makes it much easier to use the Internet less. They're poisoning the ground water of the well, effectively.
Twitter has community notes which fills the role pretty well. If an AI gen tweet goes viral it will get noted pretty fast
I think that is significantly harder to solve for without false positives ruining UX.
I don't think its bad to use AI assistance but what people clearly hate is just copy and paste.
Also its possible to generate extremely natural and casual sounding replies and comments now and you've probably interacted with several AI bots on HN already.
