Improper Format 76561198021503578

A scammer. Just want to gain petty advantages.
He gave me a HIB Android 3 gift url for Isaac and DLC(steam gifts ), told it's a bta gift. In reality, It's non-bta.
Even he euphemistically apologized to me, I would not report.
However, his second lie made me angry. This guy told me he will send me the torrent of Spirits(BTA bonus), and no mail was received in 24 hours.
When I remind him to send me the torrent on steam, he never answer me after I warned him again and again... He is just playing Dota 2 or other games...
Very sad...It just a little money.
It's rather disappointing, I must say.

Who is the scammer? -steam profiel, SteamID and so on..? -also, what was the trade for? -please provide screenshots of the trade history (My Profile -> Inventory -> View Inventory History) and also if possible from the chats.
