Something Awful also has a number of other moderation features that I think more sites should emulate:
1. Temporary bans from posting ("probation") of variable length, to allow for punishment short of a full ban. Usually 6 hours to a couple days, depending on the offense, occasionally a week or longer.
2. A nominal registration fee ($10, one time) to register an account, to cut down on bad actors just making new accounts.
3. Normal bans for being a dick are reversible by paying $10 (same cost as registering a new account), unless you get "permabanned" for either repeated bad behavior or posting illegal content. If you get permabanned, any new accounts you create get permabanned as well (assuming the admins can find them, which they do remarkably effectively using IP and I think payment info).
That last point sounds like it incentivizes the mods to ban users, so that the forums get more money. But it doesn't seem to actually have that effect, possibly because most of the mods are not paid.
There have also been a few interesting experiments in moderation that were less useful, but are definitely entertaining, such as the ability to limit an account to a single subforum (usually the one for posting deals, or one of the ones for shitposting). It's also possible to view a user's "rap sheet" of moderation actions from any of their posts.
