Call me control freak, but put me down squarely in the pro-moderation camp anyway.

I'd see a rotating volunteer corps that involved quite a large number of members who would get assignments only to fora they didn't regularly post in (nobody wants the odor of partiality, and the job should be a chore, like voting or being a bishop, rather than something to look forward to). The volunteer of the month (or whatever) in an area might, say, have the authority to move posts to a "discard pile" forum, where it could be accessed at will but not replied to. Banishment of a user could be accomplished only by consultation with the professional staff at Webflyer and would virtually never happen except in the case of the occasional terrorist.

My euro on the subject.
