I gotta admit some of Lurtzy's posts make me laugh, but when there's less wit and more plain spam... well, trolls like to be fed. It's not like he doesn't know what's constructive or not. For what it's worth though I think both Lurtzy and TH13 are all right; most if not all users here don't resort to flaming and personal attacks, the stuff that really causes hard feelings, and which might require... cruder methods.

Some forums implement a warn feature, where each user can see a warn meter (often a row of green squares) under his avatar. Each time he's warned a square turns red. If the user is warned enough times there are restrictions like a temporary suspension of posting rights. It's softer than a full banning, which I don't think any current user ('cept USF) deserves.
