I'm sure that any lists of open proxies he has available, will be available to you. Try to Google for them and block all their IPs.
Unfortunately, that's all the advice I can give. I'd hate to see an active project go to waste because Wikimedia folk are too slow to react, or because the software doesn't have adequate tools to fight organised vandalism. How many active vandals does it take for a smaller Wikipedia to receive attention and assistance? :/
