It is technically possible to block his location - but that would mean blocking a range of IPs that he could possibly use which means that other users may be affected.

However, along with reverting and blocking whatever he uses to vandalise, you can also report his vandalism to the VSTF who will take proper action just as you do.

Remember, while VSTF and Wikia Staff remain neutral, they are there to help - that means if his vandalism gets out of hand at some point, you can always ask for their help. :)
