Description:
Im making this report for my friend so here is what happened.
Team Killer Added him offered $60 for bubbling gym rat.
Team killer proposed a middle man Jo who had a fake rep page.
My Friend SuperNova got scammed and got a crate for his bubbling gym rat.

That's pretty much it, ill try to get a higher quality picture in a minute, jo is currently trade banned and for some unknown reason team killer isnt. I'm gonna have my friend ask for a trade reversal from steam support, all i know is that these arnt their mains because all the unusuals they scammed arnt in their inventories.
I know they are already reported as scammers but more proof never hurts.

Tf2Outpost you can clearly see jo currently has the unusual but it is missing from his inventory

Both accounts reported already marked. In the future, I would suggest your friend check SteamRep prior to performing high-value trades.

The banned by valve may mean that valve confiscated it, if you did make a steam support ticket, refer to that and request it back.
