Scammed by Reym

The trade was 20m RSGP for $11.
This was done via PMs

The extent of the conversation:


Bank earlier today:


Bank after the trade went down:


GE history:


It obviously wasn't sold on the GE. The only other explanation I can think of is that it was traded off of my account. The part that gets me is that I never once clicked a malicious link or gave out my password.
My interaction with him was solely via the PMs shown and in game for roughly 2 minutes with 0 words said. I highly doubt this is enough proof to get someone banned, and I know I won't be getting my money and/or gold back, but its worth a shot.

Edit: After scanning my computer after the trade, I found a removed 3 tracking cookies. I did this scan after I realized my account was wiped.
I recently recieved a PM from a user with 0 posts and after opening it, I scanned again to find 3 more tracking cookies.

 

Although it is suspicious, I can't ban him.
