I wholeheartedly disagree Fandy as Staff will get involved if a Community shows that they do not want the Admin around as if the Admin has become unpopular due to abuse in power or inactivity they can have a vote at which time if they agree they want the Admin's removal, the Admin can be removed.
However, getting involved if one or two people break that Wikia's rules or if they prove to be detrimental users to the Wikia then Staff won't get involved because each and every Wikia should be allowed to flourish depending on how that community and team works. Some Wikias work better with tighter rules and structures, others work better with more lax rules, it entirely depends and Staff back that ideal.
