If necessary, Wikia Staff, Helpers or VSTF can install a range block, which will block many IP addresses at once. Additionally, CheckUser is available to Wikia Staff, Helpers and VSTF, and occasionally local administrators can be granted this access if there is a huge issue with multiple accounts, which can determine if two or more accounts are controlled by the same person. If I can help clear up the vandalism in any way, let me know.
