Oh look its this guy again. Just because it assists you in getting around entering with 5 people does not mean its bannable because it does not do it for you. It's the exact same as group leaders joining vent and queueing at the same time that way. This guy just wont let it sink in through his thick skull.
ALSO: No one has been banned because of this addon, or has blizzard said it's against TOS. Addon's been out over a year with no problems.
