recruiter staffing spam

I am sure all of us have been inundated with highly questionable emails from "recruiters" either trying to get us to be submitted for a job, or trying to get us to hire somebody. I have found, through a test I will describe, that almost all of these emails and phone calls are fraudulent. The "recruiter" has no legal relationship with the client, and is pretending that he or she does to the job candidates so they will send resumes, then the "recruiter" pretends to have ongoing relationships with the job candidates to the employer.
