Sorry I have no screen shots, But the basic thing was I was on a normal trading server and he said 'Buying hats for steam money,' So I've been wanting to make profit from Hats for ages and Traded him. He wanted two of my hats a Purple Texas Gallon and a Purple Prince Travises Crown (painted not unusaul), He said he'd pay £10 for them and I agreed, first I checked his profile and saw he had no marks so I trusted him. I warned him I would do this and he still carried out the scam, I have had no money put in my steam wallet and he left and blocked me so I can't tell him to give me the Items back.
If this is not enough for a investigation I am sorry i'm new steam rep, and didn't take any precautions to this trade which I regret.
I hope you can help sort this out and thank you for reading.

I'd also like to say I joined him to see if he would give me my stuff back to see him doing the same thing and then claiming I scammed him. A couple of people on the server tryed help me out by asking him to return me my items but he just left left.

Sorry, without screenshots there isn't enough information to verify.
