Have we given Michael enough chances to change his ways? I just went through his user contributions, and reverted several changes to simple and verifiable facts like when a band formed or released an album when googling has revealed the original was right (or at least, assumable as right until proven otherwise). He's shown a complete disregard for community standards and has never appeared to have any desire to make a useful enyclopedia instead of a list-of-badly-written-facts-that-Michael-has-made-up-ipedia. I'm a Wikipedia contributor, not his English tutor, fact-checker or baby-sitter.
Yup, User:Michael should be banned for repeatedly violating Wikipedia etiquette. See, e.g., [[User talk:Michael]].
