I had already done a successful deal with him so was a bit surprised this time. Will try a paypal claim.
I'm sure I read a sticky on the lending board about this. They'll do a couple of small trades to build the trust, and then run without paying.
That's pretty much the habit of scammers. I've seen so many trades that sent wrong as the scammer did a small deal and then did the scamming deal with the same person.
