This video shows one of my favorite methods of griefing; role-breaking. Basically, this is going into a game where people are trying to roleplay and you break the rules of the roleplay. In here, they are playing prison break and you are not allowed to kill the prisoners for no reason. They also use the gay porn sprays like John Storm used. This method of griefing can be quite hard as there are almost always administrators in the game who are there to make sure people who are in there to ruin the game don't stay in very long.
