[alt-media-res] public wiki hijacked

[Boehm, Steffen]

Hi all, Just to say that our public wiki has been totally hijacked by spammers...
http://alt-media-res.clearerchannel.org/public/index.php?title=Special:Allpages
if you click on the above link, you'll see what i mean... these are all the pages that have been created on our public wiki... a nightmare... don't know what to do about that...
our private wiki is fine..
