Scammed by Yo Done Son

I was scammed off a santa hat, which initially I was selling for 75$ to him. He had 70+ vouches, so he insisted I go first. I went in-game and gave him the santa hat, and he said on msn it'll be a second before he pays me via PayPal. His user profile is here: http://www.sythe.org/member.php?u=202666

Here's the msn conversation:

At the end of the conversation, I gave him the santa hat and he went offline. He then deleted me as a contact, essentially blocking me aswell.

 

Insufficient proof, no paypal proof
