It has been clearly stated by SE that in the event a player/group encounters an enemy that is rendered immobile that they reset the encounter and not attempt to finish it. These guys clearly knew what they were doing and decided to take advantage of this bug. This is something that is in violation of the user agreement. They do not deserve the spoils, but instead harsh punishment for taking advantage of this bug.
