Proof

Entire Conversation Screenshots: Don't have any because after he/they scammed and deleted me from friends list I got so upset that I pulled the plug out of my PC. This will almost 100% make my "scamming allegations" fall apart. But I have the trade used, ofc "MonkeyBusiness" traded my knife "m9 bayonet Tiger Tooth" to one of hes alt accounts. I just want to find out his main account where the knife is right now.

Include any other information that may be helpful to the Trade Dispute.
So the story goes like this, "Fritz" contacted me through CSGOLOUNGE, he had a karambit doppler that he was willing to trade, IF i could get a dota 2 item from "monkeybusiness". Allegedly Monkey had blocked Fritz because of spam when he was offline. So I talked to Monkey and he was actually making it sound like me cared about when float etc my knife had.

"EDIT" I know this is 100% my own fault and I'm not expecting anything
