I have one particularly dear user that continues to create offensive accounts and pages with offensive content. (He is a known vandal of Wikipedia too.) I have followed instructions in http://www.mediawiki.org/wiki/Help:User_rights to allow editing only to emailconfirmed users. He still uses bogus email addresses to register and is able to create pages. I noticed that all his edits start with the delete template. This is a typical edit: {{delete|Stupid}} Obama Any ideas?
