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?
