When I used to play UO on the Atlantic server almost ten years ago, my roommate at the time and I would offer gates to other friendly areas. However, instead of the gate going to some place nice they would take the players to a cave with mushrooms that exploded when you walked by. People would walk around trying to figure out where they were and die after two or three steps. We would just clean the loot off the bodies, have a laugh and go back to town for more victims. Yeah it was griefing, but hey, we all did things in college that we regret.
