It might be useful to have LLMs do automoderation on forums, tweaked by the moderators to shift the discussion the direction they want it to go. Have it so that the feedback is immediately on pressing the submit button rather than after-the-fact. And probably with more useful information to the poster than the "our users don't post messages like this" message.

I think it'd be useful to ban pun threads and other low effort shitposting, but it would probably have issues determining actual expertise from faux expertise. With the wrong settings it would be frustratingly useless, but over time some useful defaults should emerge.
