Most likely, visitors to this site, want to STOP telemarketing/scam phone harassers who hide/block their number, spoof area codes, use automated recordings, and other illegal methods. These criminals do NOT check the DNC list because uh...they're criminals! The ONLY method to rid yourself of these parasites is to engage them. If there's an option to talk to a real person...take it. Don't give your real information, make stuff up, make it sorta believable. If they ask for CC numbers, make them wait while you pretend to search your mansion for your wallet...lol Ask if they'll hold on for a moment while you change your child's diaper...then say, "He's 37 years old today". Play with them and waste their time so THEY determine you're not worth it. THEY will place you on THEIR INTERNAL DNC list. I used to hate answering my cell phone when seeing an unknown number but, since I've turned it into a game, I look forward to it. Wasting their time rather than asking them to, "please not call", has reduced my phone spam by about 90%. Hanging up, ensures you'll get called again. Oh, a quick tip...don't say the word, "Yes". Be slippery...lol...say, "sure", "uh-huh", "right on", instead of a formal acknowledgement. It's been an effective strategy for me and I'm down to 1 or 2 spam calls per week. Good luck!
