Take for example NG:RP, a guy named JJohn hacked the whole server. The entire community knows it, and he admitted it officialy on NG:RP's forum that he knows everyone's account passwords, including admins too. He needs to be banned, but the staff is not doing anythint, because they know that he can destroy the community with a few clicks. So, yeah. It's possible for your GM to be stolen.
