You can't adopt a wiki if the bureaucrat hasn't been inactive for at least 2 months, and the current bureaucrat can periodically edit his user page or some other random content page just to keep the rights. The only way of preventing that is a discussion to remove bureaucrats.

Also, a little known fact is that admins can request staff to remove a bureaucrat that is inactive for more than 1 year without any consensus or discussion at all (I've actually done that at least once). Oddly enough the bureaucrat and founder claimed that they didn't have any ability to make changes in the wikia anyway. That might have been a bug or a automatic security measure that disables the "rights" until they contact support.
