I had this guy in friends list for a while, don't remember when added him, perhaps he added me long time ago to trade something but trade didn't go. So I was playing when he asked me if I was trading cs:go.. you can see our dialog in screenshot. I sent him a gift and he deleted me from friends and went offline.

Marked. Thanks for the report.
