Heritage Sports Offer

Heritage Sports Offer So I have a friend that is a prop player at Cake Poker. He gets an offer from Heritage Sports and calls to ask me about it. They put $500 in an account for him and gave him 10x rollover to release it at a max of $100 per game. He did not or has not ever deposited any money there. He was wondering what I knew about them and I told him I would ask around but all in all it looks as though all he could lose is a little time as he is at no risk whatsoever. Thoughts?
They seem to only take referrals, kind of like the credit shop I use. If you win too much, they may close your account, but they will pay you first. No reason not to use the freeplay.
I got the $500 also. I never played there either. They seem to have an address list that is taken from somewhere. They are rated B+ on SBR. They seem good so far. I am building up the account slowly cause they do have people on dollar limits for a short while.
