In conclusion: good [girl/guy] gone bad
This guy has ripped off multiple people. His threads should be deleted.
Deleting traces of his/her activity would hide such activity and make it harder for others to know of his/her history.
I assume he is long gone. It sucks when you try to do something to benefit the community and a scumbag takes advantage of things. If I was the angry type I would offer a bounty to get his personal details posted on 4chan. But that is just throwing good money after bad.
