Well I just want to report this user for scamming.
Basically he wanted a Dishonored 2 Steam CD-Key which I gave to him and after that he tried multiple times to avoid being reported, but in the end nothing worked. First he said it is a DIRT 3 CD-Key, which he failed to prove, because the screenshot that he sent me showed that he activated Dishonored 2 on his steam account. Then he said steam servers were down, when trading was perfectly fine, because I was able to send him a trade offer and also he was able to put the keys in direct trade, which he canceled afterwards. In the end the trade offer I've sent to him was declined it and he said "done". Oh he also made his profile "private" after the trade was done.

Sadly SteamRep removed my report simply, because they do not deal with CD-Keys anymore.
