Is sizzlefizzle.com a scam?

Tweet

My friend is a member at this site. She has reached the payout 2 months back. She had redeemed the earnings, but has not been paid still. It was siad that she will be paid in the first week of July. But not still..Has anyone here been paid by sizzlefizzle? How long does it take to get the earnings? Or is it a scam site?
