It isn’t condoned, Ahndrumon, but neither is it technically against policy. We simply aren’t able to micromanage social interactions to that degree. It just isn’t feasible to weigh in on countless dungeons, scenario and raid runs to figure out why a person was removed and if such removal was justified.
The Vote to Kick system isn’t perfect, but it has helped to address a lot of the negative situations that used to happen. The positives of the system since it has been implemented have far outweighed the occasional negative when someone opts to be a jerk.
If you feel you have an idea of how to do it better, without the need for Game Masters to step in and micromanage social interactions, feel free to post over in the Dungeon, Raid and Scenario forum.
