I just spent again 15 minutes removing spam from the wiki. That's not 
really fun.

Adding a new user account should require confirmation by mail. This 
extension
can also help a little bit: 
http://www.mediawiki.org/wiki/Extension:AntiSpoof.
Even more restrictive would be 
http://www.mediawiki.org/wiki/Extension:ConfirmAccount.

And the wiki still needs administrators who are allowed to really remove
spam pages (try http://wiki.qemu.org/Special:ShortPages to get the page 
titles).
