I was talking to a person, he said he was buying unusuals for a fair price. I agreed, and offered a bud for an item. He very generously offered $240 for my three unusuals, which greatly surprised me.
He insisted that i go first, and sent many trade requests. He said that he had wanted these hats for a long time, and that I had nothing to worry about, as he was an experienced trader. He had 0.7 hours on TF2 and no comments on his profile, and his inventory was set to private.

My computer crashed, and so the chat history was lost. When I logged in again, he again insisted that I trade him first, and then he use his verified paypal to pay me in full. He did not give me his paypal email. When it became clear that I was not going to trade him first, he suddenly unfriended me. When I began the process of a report, my computer crashed yet again, and I was unable to obtain any screenshots.

Without screenshots, it is merely hearsay. There is no way to add additional notes to the profile.
