I don't think so. I think they will appear to do a good job because you just won't see all the false positives and biases because it's obviously been moderated/censored.

How do you PM the AI moderator to argue your case for reversing suspension?

There are two rules that make it infinitely easier to moderate/manage a social internet group: no politics, no religion. Done.

I'm not sure what your second point means? People will be happy to converse unknowingly with 'AI'?
