I doubt that a rogue moderator would receive express advance approval of abusive actions. If Eliezer says that Alicorn may ban certain comments, then it is not abusive for Alicorn to ban those comments.

If Eliezer's approval makes the action tautologically non-abusive then please act as if I substituted a different word that means something along the lines of "detrimental, innapropriate, politically ill advised, deprecated and considered 'naughty' by user:wedrifid". ;)
