Scammer got me a year or so ago. I made the mistake of putting my email address in my post. I received a couple of replies, one was for 50.00 and I sent it...still no card, the other I contacted Leon about and he told me to be very cautious and to ask for their Network54 ID. I did just that. The funny part is, they replied with a user ID of SB1....
Which even I knew was Scott Brockelman.
Don't post an email address and I think you can avoid 75% of these dirtbags.
