I'm sorry. I'm not an admin. I will give you three pieces of advice though. First, edit other pages and keep away from this guy. Second, if you can't do that, get a new user ID just for those pages and try to stick within the policies of Wikipedia. Don't let the guy in question know that you're you. If another user breaches the policies, note it on their talkpage politely and make a note for the case you will later bring against them. If he protects pages he's editing, blocks you for disputing content, anything like that, then note it. Just make sure you personally stay within the policies, stay cool and stay polite. Third, start an RfC. You'll need to find someone else who has also suffered at this guy's hands. If he's as bad as you make out, it won't be hard to find someone. If the RfC doesn't bring an outcome you can live with, take your case to the arbcom. They will almost certainly back the admin and make out you are full of shit, so if you go that route, just lay out your evidence and walk away. Don't get involved. Don't let it get to you or make you mad.
