bans are always a fucking retarded approach. you should encourage the behavior you want to see rather than trying to ban the behavior you disagree with. if you reward people for the right behavior, they'll try to maximize the right behavior to reap the rewards. if you try to punish people for the wrong behavior, you just end with people putting all their brainpower into trying to find ways to dodge the punishment. excludes some shit like murder and so on of course, just shoot those in the face.
