i got scammed by: http://steamcommunity.com/profiles/76561198085594537/
i have the screenshot of the chat where he promised me items for my minecraft premium account's password and didn't get anything, the chat in the screenshot italian, but i'll translate it:
zSandro:now i'm sending him (the middleman(?)) the items.
zSandro: c'mon mate
zSandro: ooo
me: wait i'm talking with your friend (middleman)
zSandro c'mon i'll give you the objects if you give me the password
(i trade him he accepts and puts some stuff in the trade)
zSandro: now the password
at the end anyway i tell him the password (vaffanculo1) and he deletes the trade and i'm not fast enough to change the password... everything in the screens
