I mean, we really can't know for certain if what you're doing is going to get you banned or not. In this case, you don't even mention which buff it is, so if there was something unintended about it perhaps we'd be able to tell you something, but since you don't mention that... it's kinda difficult.
How is it possible that a Blizzard staff member does not know something a player does will get him banned? THIS is why many people feel that things are enforced so arbitrarily in the game. Is there not a list of gray areas that Blizzard has behind the scenes that should be consulted instead of this being left up the to mood of the GM you happen to run across?
