But he is not a true admin, his title just says he is. He has access to the FTP for working on his hack or something, and he "hacked" admin status.

He's not technically an admin, he's a Supreme Mod, he just made it look like he's an admin. If he wanted to, he could do what admins do though, just in a different and probably much more complicated way(modifying stuff in the FTP thingy or whatever.)
