Soo I made a trade selling some stranges, after like a minute or so I've got a friend invite, it happens that this guy called "♥♥♥♥" wanted to my stranges, so I invited him to trade, aaaannndd he was on a Trade probation (probation is basiclly a time after the trade ban) it was suspicous so I check his steam rep, and it happens that he was a scammer.
