And I'm worried banning AIs altogether will eventually lead to some form of prove-you-are-human verification to use the site, which will reduce anonymity. Even something seemingly benign like verifying email would mean many unverified accounts like my own will disappear.
And there is a legitimate use for LLM rewrite to counter identification by stylometry, so rewrite shouldn't be banned. I think we'll have to allow the AI stuff at some point, and make a system that incentivizes quality posts regardless of where they come from or how they're written.
