When you answer and say hello to a robo-dialer, thats what tells the robot that it is a working number,and that it has a live sucker on the line, and your number is then moved to the"sucker"list,once your number is on that list, it stays on FOREVER! Welcome to our little club.Your number will be sold/traded/shared with every other scammer here in the USA and perhaps around the world. You can complain/biXch/and moan all you want to the FBI,CIA,NSA,FCC,FTC,OPRAH, and even Hawaii 5-0, but your number will always and forever be on the"sucker list".When they call,consider it a challenge or a sport,mess with them with the goal of wasting as much of their"valuable"time as possible,press 1 to speak to a"representative",then feed them as much B-S info as possible,give them goofy/FAKE names,addresses,credit card numbers,toll free customer contact numbers on the back of the card,etc.etc.Since I retired,one of my personal favorites,is,when they ask for the toll free number on the back of the card, I give them a VERY kinky toll free sex-chat number,(google for a list of these),then just wait for them to come back on the line.Hilarity ensues,but be prepared for their true evil personalities to emerge,hold the receiver a couple of inches from your ear in case they have an air-horn/whistle.I've been messing with them for about 5 years now and actually look forward to their calls,I usually average about 10-20 minutes per scammer,here's my routine,I pretend to be senile and/or hearing impaired,and make them repeat things 3 or 4 times,but remember,they are trained professional grifters,their ultimate goal is to get your checking acct./credit card/debit card info so they can transfer your money to them.My husband tells me I need a hobby,I tell him I already have one.It's called scamming the scammers.Stay safe out there fellow club members.
