This was the trade window, and I added him only so I could keep him as a contact if I didn't get the money. The moment we traded, he left the trade server and deleted me from his friends list. After that I was unable to contact him again, http://i.imgur.com/ethpD.png. I also joined the server he was on afterwards and he rejected my trade request instantly and left the server.

Description: I came across this person in trade server I often play on, and he said he was buyin Bills', BMOCs, as well as other thins. In the trade window he then told me that he was buyin them with paypal. We decided on 19 dollars and some sweets for my #40 crate, which is now clearly visible in his backpack. http://i.imgur.com/pXpSn.png I asked him to send the money first, but he said I could check his profile and I saw a comment saying he had done paypal trade successfully, so I somewhat foolishly I agreed. I added him, but the moment we traded he deleted and blocked me, http://i.imgur.com/ethpD.png, and left the server. When I joined the server he had gone to, another trade server, he declined my trade request and left the server.



This is my trade history, clearly showing my most recent trade.

Also, this is the server I was on: 37.220.1.218:27015

To be honest this is the first time I've ever been scammed and I don't know what to do. If anyone can do anything to help me, I would greatly appreciate it.
