Yeah, they're all over. Every Game(not the old Intertops), DailyPayoutBook, 7Stacks are just a few. I've seen dozens more. When you request a payout you basically get paid from new deposits so they don't handle the money. So if they ever get in trouble with the law it looks like you were accepting deposits for them. Not something you want any part of.
THEN they make you re-tweet their shit, post positive reviews, etc. You have people shilling just to get their money. It's ridiculous.
