You could request to adopt the wiki on Community Central and recieve Admin and Bureaucrat rights on it so that you could block said user or at least revert their edits more easily or ask another mature user to adopt the wiki instead. However you or said mature user would have to meet the various adoption criteria if you/they were to be given the Admin and Bureaucrat rights on the wiki.
