Description: This guy approached me interested in a copy of Shoot Many Robots that I owned and posing as a employee of a cdkey store (www.buypcgame.eu).
I'm interested in the on-going Saints Row 3 promo so I saw this as an opportunity of getting the game.
I checked his SteamRep (which is clean, shows a few scammers as friends but in previous experiences this hasn't meant anything as to the type of trader I'm dealing with), and his profile is full of (what I now presume fake) testimonials of successful trades with them going first.

So I offered to trade him SMR+5 tf2 keys for a SR3 key. After I transfered the goods, he said he was getting the key from his store and then promptly deleted and blocked me from Steam.

I made a mistake and let the opportunity at a cheap game get the best of me, but I don't want other people to be fooled by this person.

Thank you for your time.

Here's the trade history.

I should have checked this thread first. I got scammed by him with a Dead Island key. Damn.

Marking now, thanks for the report.
