Improper Format Scamming Impersonator

http://steamcommunity.com/profiles/76561197989005120

This user wanted to trade me his Dishonored steam key for my giftable games Alan Wake Franchise and Death Rally, and since his steamtrades rep was like %98 positive I trusted him. After I traded my games he sent me an invalid key and blocked me.

After some research I found out he was an impersonator and not the actual owner of the forementioned steamtrades profile. The actual owner is: http://steamcommunity.com/id/detruire

Edit:

Victim: http://steamcommunity.com/id/the_auror
Scammer: http://steamcommunity.com/profiles/76561197989005120
The person the scammer impersonates: http://steamcommunity.com/id/detruire
