I was a loyal customer for a good 6 months then he ripped me off $400 when SR2 first came up. Quite a few others were scammed too.
I know it's him as his PGP key matches up the old one i have saved and his profile layout is the same.
What action should I take???
You should tell us who this monster is. If you don't, then other people will be scammed by him.
