Reporting Istah

Scammer's profile link:http://www.sythe.org/members/404373-istah.html
Explanation of the trade:I was selling him Ikov gold, first 2x 2b increments, then 2x 4b.
How they scammed:He paid for the first 3 increments but for the fourth one he claims I never gave him anything. After I told him I would file with a scam report, he threatened to DDoS me.

He also confirmed he was indeed on the Skype account Istahj by posting that he had sent me the money for the first 3 increments:

I can't show uncensored versions of the logs publicly as they show my game account names, but I can pm them to a mod at any time.
