Mmm... I am not a sysop so I cannot decide anything in the matter, but I bet this wikia is fairly small and does not have an activity high enough to justify more than four admins. The activity is so low that Masson Thief and Unnamedgoon even do not leave any troll to block to poor Luigitehplumber. Also, Fandom would not like a small wikia with too many admins, I guess. That could change if the wiki will grow, though, and this is not an official response.
