If you have ever answered a call from these scammers you are on the list. Sometimes I answer them. I go to this site and generate a fake ID. Then I play their game. I give them all the info the site generates including a CC number. After they type all the info in and the credit card number doesn't work my answer is "you been scamed scammer" and hang up. Try it some time. Tell them the number has been reassigned and you want to know about the scam. The site is: http://www.fakenamegenerator.com/ . Enjoy !
