Just traded with him, I feel slightly cheated. I explicitly asked him if the key was in a certain format, and he said yes. About an hour later, having to pay in an overly complicated way, I got the key, and it wasn't in the format that he told me it was in.
Not quite a scam, he did send the key, but he did lie about it, so it wasn't as he'd had me believe, and he signed off/blocked me as soon as I queried him on it. I'm considering this to be my first bad trade here on Sythe.
Same happend to me.I wanted a DoW key that would work with steam.He replys saying yes the "universal key" works the most with steam.He gave me the key and it did'nt work.He then demanded that I pay him something.
I also posted the cd-key on my msn so everyone can have it.Since thats what it seems like you wanted seeing as you've given it to 3 different people now.
