I know this guy, he has scammed 14 TF2 keys from someone I know, and we gave him -rep on his profile, we only removed the rep because he has gave back the TF2 keys (with an extra key for the problem), and said that his "brother" has entered his Steam account and stole the TF2 keys.
But after this incident I'm starting to think that all of this "brother" thing is a complete lie.
He's definitely in league with other people, another man messaged me that I edited into my -rep on this guys profile, though sadly I didn't get screenshots because I was kinda too pissed to do so lol.
The worst part is I even said I'd be okay with getting half of my shit stolen and would even remove the -rep if he gave half back but I guess he's too far gone, and this puppet account is gone too.
My own fault for not knowing that you should always always ALWAYS search someones steam URL before trading with them, and not just a cursory glance at this website. Live and learn I suppose.
let me know, quickselling it
