I think that the (dead, gay) Something Awful forums model is a decent solution to content moderation and monetization.

An account is 10 dollars (lifetime). If you get banned, you have to pay 10 dollars again. Permabanned = can't come back.

Premium? (dms, search, custom avatar) 10 dollars.

Change your avatar? 5 dollars.

Change someone else's avatar? 10 dollars.

Ad free? 10 dollars.

Access to archives (posts over a certain number of years old) 10 dollars.

Not too expensive and no recurring costs for good citizens, prohibitively expensive for bots/trolls.
