Evil overlords of computerized activity. Will ban just about anyone they don't like, even if they follow the rules flawlessly. Nazi administrators are generally megalomaniacs whos lust for power overwhelms all sense of judgement, which ends up resulting in terrifying abuse of admin powers. Examples of Nazi administrators can be found at the forums of Sonic HQ, and even here, where the Nazi administrators compulsively delete definitions by request of their other Nazi contacts.
Nazi Admin: Sieg heil!
Innocent person: What?
Nazi Admin: That's it, you're banned!
