The page-move vandal WoW is back again. this time as [[User: © http://en.wikipedia.org/w/index.php?title=User:%A9&action=edit]], an account kept from August 2004. So clearly WoW has some "old" accounts still registered, and regards them as throw-away accounts.
Could a developer or bureaucrat please take a look at the logs to see where this nuisance user is coming from, to see if there's a consistent pattern of IP addresses?
