Revolve put it perfectly. The avatar is global across Wikia: you can't even enforce something like this. It is not our duty to warn users when they're putting questionable content in their masthead: if a masthead violates the Wikia TOU (the only thing that controls masthead use), you report it to Wikia or VSTF and let them deal with it.
