"Yellow let it mellow" scammed me

Yesterday I was buying a RuneScape membership pin and I came past yellow let it mellow, I added him and we talked on MSN (conversion below). I looked for an MM but couldnt find one online so I just went forward with the trade. I gave him the money and I see his MSN status is offline, meaning he blocked me.

I PM him saying I want my pin or I will report him, he replies with this:


Here is proof of trade:


Here is when he "went offline":

Bump, he has been scamming alot more people, please ban him before he does more harm.
