This appears to be a spammer.
Administrators may want to check the user's contributions to see if there's justification to the claim, the history of this page to see how long the allegation has been undisputed, and perhaps look at the block log before waving the banhammer. Or, maybe just pause to do a better hack-code on the underlying Template:Spammer, y'know.
Non-admin users can use this template for User/UserTalk pages that you feel are associated with a spammer account and thus should be banhammered by an administrator. See Category:Spammer for a list of such alleged spammers.
