Today I've got contacted over PM by just-registered, 0-post, empty profile user Kinsje in respect my old "In Search Of" posting. He referred to another alleged forum member davi754 who supposedly has the part I need, and provided his phone number. I've contacted the latter person, and he wanted $150 for preowned $30-part. But then I did member search over all possible combinations of "davi754" and couldn't find anybody.
Thinking about it all, such combination of factors is rather impossible in normal situation.
So my understanding at this point is this:
- someone is scanning through random forums looking for "ISO" postings;
- registers, sends PM referring to another fake forum user to build trust, gives his own cell phone;
- negotiates fake deal (not even knowing right price point as we see), receives money, disappears with no trace.
As a side note, some other forums I'm part of, require new user to have certain amount of postings and the profile filled to certain minimum with validated email before he can send PMs (although still not a guarantee against fraud).
Be aware everyone !
