Sorry for your loss OP, but it's nothing new. This specific user has done this multiple times in the past. He takes a couple of hundred or thousand dollars from members via scamming > gets banned > creates a new account > buys a Premium Membership > and then repeats the whole process again, usually once a month.
We, the older members, often know what's going to happen weeks in advance. I personally reported him about two weeks ago, but on this forum, proof and a Dispute Thread are needed to get someone banned for scamming.
