People who get Unfunnied have to stop contributing to CPMC while the group membership lasts. Seems like that's not very good unless the person in question is, well, really unfunny. I do think another punishment would be useful.
I have an idea. Not sure whether the forum software would permit it, but I might as well put the idea out there anyway. I'm envisioning a "Chew Toy" user group whose members can have their avatars and personal titles changed by anyone. Or better yet, maybe only those within the Idiot Hierarchy could mess with a Chew Toy's stuff. Could that sort of thing work?
