I updated my Resume to say "Don't use the Message Center". 95% of the creeps who use it haven't read my Resume anyhow and spam me with Windows Sysadmin jobs. I block them.
Also another Monster dumbshit idea is BeKnown which I think is their DOA answer to LinkëdIn. Another gem is the "Apply to FlyByNight College X" page which manifests itself on their US site.
