He's not a scammer. He's dealing with idiots every single day (uploaders) not webmasters. Uploaders in general are stupid and request a refund when then can't get something to work. After that they generally read the instructions. You only hear people with issues but 99% don't have problems.

As for KWWH he left it and started another Webmaster site and had an argument with staff here.

EDIT: the topic you linked to is months old anyway.
