One particularly effective way of dealing with trolls is when identified, add them to a fishbowl of sorts. Anyone in the "fishbowl" sees all of the crap tags and mayhem, but all of us in the real world don't. If they don't realize they're being circumvented they're a lot less likely to change their tactics. In the case of Gelbooru, it would probably also be effective to add any tag, edit, or image created by a "fishbowl" account to the bowl - visible to them, but not to us. If an account creates a large number of known bad tags, they get added to the bowl automatically, or at least nominated automatically to an admin.
Ban them and they'll come back. Undo the damage and they're redo it. Undo it but make them *think* it's still there, and the problem is largely eliminated.
