Scammer: SpacedLlama

First off, here is his vouch thread. He has around 50 vouches, and I even did about 100$ worth of business with him before. I didn't think this guy was even a potential scammer, but I was obviously wrong. I'd like to see this guy get banned, very quickly. I'm so irritated because I gave him items that I could have sold for over $1000 USD, for an amazing deal of only 150M gold on RuneScape, which of course he did not come up with. Instead, he logged out.
Proof:

Link to scammer's Sythe profile: http://www.sythe.org/member.php?u=241077
Briefly explain the trade: 100,000 vote points on Near-Reality private server (me) for 150M RuneScape GP (Him)
How they scammed: I gave him the items, he logged out
Proof that you were not talking to an impostor: Look at his signature, and the person I'm talking to.

This guy is such a lowlife. I also messaged him on the forums without a reply in an hour. He also has been logged off of MSN for a long time, despite he is STILL logged into Sythe.

Please, please, please take action. I never want this to happen to anyone again, I'm very stressed from this.

Thank you.

 

Already banned.
