Thread:Project:Support desk/Hacked page, unable to delete

There is a page that was hacked in order to post malicious content about a certain United Nations executive. I used WhoIs to find the MediaWiki owner and contacted him. He said that page was put up under their MediaWiki without their approval, but they can't seem to delete it for some reason. Can someone at MediaWiki please help us take down the hacked page? Thanks.
