Briefly explain the trade:
I offered a gift copy of the game Counter Strike: Global Offensive, we agreed on $40 for the game.

How they scammed:
After offering to go first, he asked for my paypal address and then just blocked me off steam.

Proof that you were not talking to an impostor:

(He might argue about that he didn't add me but check the the time of the end of the chat and the time of the pm)

Trade screenshots:



The I PM'ed him but he started arguing that he wasnt the one who added me



But that was clear because we replied when I asked him for a PM.

If you need more info please tell me, thanks.

 

He is still trying to scam people, at least I've got his account banned from Steam trading.
