The way I see it, he was clearly exploiting game mechanics to grief other players. He was using a specific ability, one that teleports players, to teleport them in front of what appears to be an unkillable robot that instantly kills everything. After he was done with that, he "innocently" taunts them. I'm pretty shocked that NCSoft didn't do anything about this. In other MMOs, that person would've been banned a long, long time ago. I played CoH for a bit, and I think it's still one of the nicest, casual MMO communities around, hell, one of the nicest, casual gaming communities around. This guy walked around a virtual community, disrupting it on purpose just for an experiment. Imagine coming home after a pretty long day of college/work, log on to play, only to have someone permanently teleport you to death, and then taunt you.
