Key he gave me: G6H47-TBGRT-NATM9

Description:
I had a post on SteamTrades about my Killing Floor bundle, and he had added me offering LA Noire CE for it. He said he also had SR3 and MW2 keys. I had taken the SR3 key, and we went back and forth a bit about who should go first (he had 9 +reps and I only had 2, even though I've traded many times before. No one leaves me +reps, even if I ask them. :U). After I gave him the KF bundle in Steam trading, he gave me a used Lucid key (thanks a lot, reddit) and then deleted me. His profile is private, only viewable by friends.

Right now there is not enough information to warrant a scammer tag. If you could provide anymore, it would be much appreciated.
