the masterpassword can't really be used to mess w/ someone's turn, w/out it being completely obvious (since he'd have to do the whole turn himself, and it would bear little relation to what you sent in).

however, it can be used to illegitimately scout out an opponent's empire. I wouldn't worry about it if the guy is personally known by someone else. You have to be on the level of a norfleet to do that.
