One of the contributors to a small wiki I admin is extremely stubborn and will revert changes made to his edits even when they are demonstrably wrong or inferior.

He also is completely uncommunicative - he doesn't respond to messages left on his talk page, regardless of how friendly or diplomatic.

I don't like the idea of blocking someone, but I don't seem to have many options in preventing this uncooperative behavior. Is it the thing to do in this circumstance?
