>If people can flag anything they disagree with a little effort the community can be AI free at least on main page

Unfortunately AI-based articles are on topic (AI generated comments are not) and if people flag them they'll just lose their flagging rights. I'm also reasonably certain "flagging campaigns" are categorically against the rules, even though there is such a campaign implicitly against "politics."

There's nothing anyone can do about it except complain (which will eventually get them filtered because such complaints are also against the rules), be quiet and tolerate it (which is the only option that follows the guidelines), or else leave to greener pastures.
