Edited: I'll leave this as negative rep, since I'm still not believe you.
I go first with my unreveal key page of Civilization 6 (the dumbest thing I've ever done), and he said it was already redeemed. I asked for the picture of his games libary to prove that he didn't have the game, but he can't and just keeping talking around to hiding something. After that, he said that he gave it to a friend and his friend said it was redeemed (very suspicious, isn't it?). I asked again of the steam profile of his friend, and he still can't give me. Finally, he gave me some picture of email that he wrote to Humble Bundle, and insisted that Humble Bundle had given me a redeemed key.
Now you removed and blocked me. Man, you have all of suspicous about being tricky. So I will find out the truth and will change this review if you're not the one who cheated on me.
Edit 2: Thanks GaTh for gave me this picture. https://steamuserimages-a.akamaihd.net/ugc/770615135469301697/34402272E4C4C000B9657126FE6ECDDA03354C94/
You hided your games libary, and the picture above showed my Civ VI sitting in your libary, that was totally unexpected huh? If you can prove that Civ VI wasn't redeemed today by taking a picture of your history product key activations, then I'll remove this review. Otherwise, I'll report you on all trading sites that I know and also on Steam.

He added me again, refused to give me proof and admitted that he stoled the game from me. Stay away for this asshole guys.
For starters i havent blocked you and i gave you 3 keys for trades, so now you and the other guy are teaming up for no reason when ive done nothing wrong? Also i already have the game but wanted a spare copy for a friend to play hence why i gave it to him. gives me a negative review but then does a second trade after this one so clearly writing false reviews. Okay so people cant get new games anymore without them being stolen? you and the other guy have both done this to ruin my rep dont lie. Not once did i admit to stealing your game, jeez people these days.
