Since I started vaping a couple of years ago I have opened a new credit card just for vaping supplies etc. Today I received the third call I've received about someone in a totally different country trying to use my newest card. All three times the charges were refused and the account closed so no loss to me. What really disturbs me is that the cards were used ONLY by me to order vaping supplies from ECF suggested sites and once in a while Pay Pal. I read somewhere that the numbers are probably acquired through a random number generator. I could ascribe to that theory if it only happened once but today is the third time in 24 months on 3 different cards. In all my years (and there are a considerable number of years) using credit cards for gasoline, travelling, clothing, furniture just whatever I've NEVER run into this problem. I did not try to become "verified" until a couple of months ago because at that time the only way to be approved was to disclose my banking information to PayPal. There was no way I was gonna do that but then I saw that the NetID had been added and they at least didn't want an open door to my checking account. What if I had given PayPal my banking information? I already know the answer...........SOL. There's a leak somewhere and it needs to be found and plugged!
