Can AI Bots Poison a Forum Without Posting Spam?

[VB]

AI bots do not need to post obvious spam to damage a forum. They can nudge discussions, repeat half-true claims, create fake consensus, quote users out of context, or slowly make real members tired of replying. A forum that wants to stay healthy needs more than spam filters, because the real problem may be behaviour that looks almost human but keeps lowering the quality of the place

This is more interesting than the usual spam discussion because the bad posts might not look like spam at all

Fake consensus is a real risk. A few convincing accounts can make a small forum feel like everyone agrees

Moderation gets much harder when the problem is tone, repetition, and agenda rather than obvious links

I think communities will need stronger identity and trust signals, not just better captchas
