Sometimes I call the toll free phone numbers that show up in the SPAM. I give the person sh_t for about 10 minutes. They tell me that they aren't sending SPAM. When they say that they actually mean that they hired another company to send SPAM for them or that they were hired by the SPAM company to take orders. Anyway, a half-truth to try and deflect criticism of themselves.
I did get a hold of a local addiction treatment center that was SPAMing my company. They swear that the salesman from the SPAM company told them that the emails would be very well directed. The SPAMmer lied to them. After my call SPAM from them stopped.
