"Telemarketer" nowadays means just anybody making annoying calls. I don't remember when was last time somebody who actually wanted to sell something has called. All the calls I am getting now are either asking for donations (which are exempt from do-not-call law, being a "charity"), doing a "survey" (also exempt) or are from criminals helping with my "credit card debt" , from "Windows security", from "IRS" etc. I imagine the criminals, already breaking more serious laws, would ensure they are not vulnerable to the do-not-call.
