for best effect, don't worry dude this guy is going down!
Use my screenshot if you want, I'll report him tomorrow.
Now I just want him to die slowly and brutally
No please do it as soon as possible before he ofloads your game to another account and it is gone forever...
Well, I reported him)
but I have a bad luck.
Today I won my first giveaway and few hours later was scammed by that fag
Yeah I understand your frustration, but I have heard of cases where steam has returned unopened gifts, so if we are lucky, you know, just don't lay down and let him rape you, did you report him to steam support, because they the only people who actually do anything about it, You will be #6 victim on steamrep and this guy still has his trading rights, that website is useless.
here's a link to his profile.
