Much in the way that "they did it on Voyager!" is never a valid answer for a star trek rebuttle, "Someone else did it first so it was ok for me to continue" is also not the right answer. The correct response is to stop, report what they did wrong and let us handle it. If you continue with it, you are part of the problem. If you get asked by an admin to stop doing something, and you keep doing it, you become MY problem.
Emotions are running high in here at the moment apperently, so I think we'll go ahead and close this for now.
