None of the above. I prefer locking them in a no-recall room with an unattackable mob that just keeps saying, "I like swords.," over and over into oblivion. Annoyed to death, worst way to go.
I don't do anything brutal, just fix their Wikipedia ads and stuff. I guess the closest thing from that list would be forced self-mutilation, which may or may not happen depending on how depressed that they might become after being corrected. Though, that's not really forced I suppose.
Had to go with "Force to stop mudding" because, afterall, you did ask regarding unwanted mud community members and, well, the rack is fun not brutality.. :evil:
