The bad ones will never tell you outright, too worried you'll cut them out or tell your other recruiters. I have a couple of good ones I pretty much deal with exclusively. If I get a spam op from another recruiter I'll tell my real recruiter to go pitch me to company x (if I'm actually interested).

Sure its pretty ruthless but its not really my problem these guys look out for me and only bother me with calls about companies they know I'd fit with. They also leave me alone for years on end until I initiate the "I'm looking again" "protocol"
