There are a very few number of books that I have actually personally endorsed to my friends. Those books I have referred probably referred 20 or more people that have actually signed and deposited money. I have steadily earned money at those two book over the past five years but I received any sanctions such as lowered limits put on phone wagering only or taking away other perks.
im not sure what u mean.. but of course u bringing business to the sportsbook helps them especially if ur friends lose. lol and if they do consider becoming an affiliate.. instead of earning 15% or whatever on one deposit u can earn that and more on every deposit/loss ur referrees endure for lifetime of them betting there.
It is all debits and credits, books don't care about your reputation. You and friends lose - you're good customers. If you win - they will try to kick you out.
