Info:
His profile is full of comments of guys that got scammed to him, in my last attempt i posted the trade with had with dishonored, i gave dishonored on a trade to another guy, some time later he informed me that the game got revoked, then later, support informed him that the game was bought on a stolen card, he did this to over 6 persons and he is still not banned here.

User who got dishonored revoked : http://steamcommunity.com/id/freemind6666/
Also got his game revoked : http://steamcommunity.com/id/bekyi
Got 2 games from him, both revoked : http://steamcommunity.com/id/m0rgana/

I know m0rgana and his account was disabled because of this (now after a week it's working fine).

Why was he punished and not that guy johi**joni who bought games for trade? They used steam trades window and m0rgana's games should have been given back to him.

Reply from steam support was: don't trade with people you don't know.

And they have a sub-forum named Steam Trading...

Steam , doesnt investigate things right, thats why im posting this here, so he can get marked, and people check it here before trading with him, when i traded with him, his steamrep as clean, so i went trought, i hope he gets marked so no one gets scammed from him again

*The trade we had with dishonored, (...)
