The admin on the wiki I help to edit has been having problems with a spammer who edits the pages with unncessary info. She has tried to IP ban him, but he can easily bypass the ban with a proxy IP. Is there any advice on how to handle something like this? I was wondering if the Wikia had the option of validation upon account creation (where the admin would have to approve of a profile upon its creation, before they would be allowed to edit things).
