What happened? Description:

I added a trade on CS:GO Lounge (https://csgolounge.com/) and then the scammer added me on steam. He said he wants to buy my knife via paypal.
During the conversation he made clear to me he is a trusted "middleman" and "buyer/seller". I trusted him because of the +reps (didnt know they are all fake) and the description on his profile (steam level 100+, many +reps , 101 games on steam etc.).
Then he said he will prepare the PayPal process. Two minutes later he sent me the screenshot number one and said he'll click accept after receiving my knife via steam-trade. He also sent me his PayPal history as a screenshot (number two). At this point i trusted him and sent him my knife. He accepted the trade and said i should check my PayPal because of my money.
He blocked me and the money wasn't transferred.
I closed the chat instantly so i didnt make any screenshots of it unfortunately.

On Tuesday, three days later, a friend contacted the scammer and asked him to give me the knife back. The scammer also admitted the scam (screenshot number 3), but didnt send the knife back.
