This son of a bitch. He wanted to give me 125 keys for my knife, he said he needs a middle man, I only had buddy online, so I gave buddy my knife and buddy closed our chat.. that motherfucker went to the other account and changed everything to be like my profile and buddy didnt check on him, he made a trade request and booom the knife is gone.
I sent steam support a ticket.. I just hope i get it back.
