I'm not concerned about a pathetic local GUID ban, I am only wondering about global bans and the circumstances under which they are being handed out. I know it was a complex question but if you don't understand then please don't try to answer.
Since I have gotten banned and then unbanned myself from non-DayZ servers after the DayZ-related global bans began, I know for a fact that not every BE ban is global.
Since the BE people would have to look at each mission script before making restrictions for a particular server, and they don't all share the intimate relationship that BIS has with DayZ, I'm going to assume that the answer is no, global bans have not been handed out for anything aside from DayZ.
