Why would people lie and say they hadn't been paid? That doesn't make sense.

If this site wasn't a scam I'd be encouraging more and more people to join in. The more who join means there's less MHS (neé KHS) to go around. The scarcer the resource gets the more value it has. The value of my account would go up the more people there are trying to join the party.

By saying the site is a scam people aren't trying to cheat anyone out of money. They're trying to stop you losing money. Yes, you've got paid but that seems to be a mistake rather than the norm.

This site is a scam. Pure and simple.
