Some extra extra advice: If you can get a problematic user to at least agree to discuss a set of rules for governing behavior then that user can probably be worked with and turned into a mostly productive user. If the user won't even agree to discuss some constraints and why they need to be in place, sometimes a long (or maybe short) cooling off ban/block is the only useful recourse.

It is also good to get other (especially the active, respected ones) users in the wiki community to agree with the rules and make sure they are being applied consistently. If a disruptive user senses they are being singled out for something that other users are doing or they believe other users are doing also, the process is in trouble.

Otherwise I agree with all 452 said.
