You can ask Wikia to semi-protect the category namespace against IPs and new users. It can happen. They offered to do it for a wiki I work on, although we didn't think it was right for our particular problem. This might prevent much of your problems with people messing with your system. Ask Wikia to do this through a special:contact message.
