I'm not very familiar with Everquest. Was there any in-game law enforcement to punish players doing this? Vendetta? Assassins for hire?

We used to train players who pissed us off. In everquest creatures had a tendency to switch who they were attacking pretty easily. So you just anger a bunch and dump them on the offending player. They call it "training" because you have a train of creatures chasing you.

Training generally wasn't punished because it happened a lot on accident.

On reddit there was a recent set of stories about hilarious training and glitching and so on. This might give you a chuckle: http://www.reddit.com/r/gametales/comments/1cy607/everquest_...

were different rulesets in play(who could attack who, what could be gained in the process(money or gear), pvp was really an afterthought for them.

I can say though that in persistent worlds there is always a history, usually fresh "meat" too though.
