You are asking to get scammed. Idiocy at it's best
I'm asking? Really? Buddy didn't even check on who is he talking to.
Steam also said this : Unfair Trades and Item Scams
You participated in a trade where you felt tricked or deceived. Your trade partner was posing as a reputable middleman or friend. There was money offered in exchange for your items.
https://support.steampowered.com/kb_article.php?ref=7623-IOFX-1021I thought buddy know how to be a middleman.. but..
Anyway, that guy used my name and my profile settings + the avatar to pretend to be me which it's not allowed and therefore I should get back the item. Hopefully they just answer my steam support ticket.
