Professional sports bettor Mike Manning says he got a firsthand look at how a sports gambling betting platform treats winners differently from losers. He told CBS News’ Jim Axelrod that Caesars Sportsbook showered him with VIP perks when he was losing, then slashed his betting limits and cut off the perks after he started winning. His account adds to allegations that sports betting platforms limit the amount skilled gamblers are able to wager. In a statement, Caesars Sportsbook said, “We don't comment on the specifics of individual customer accounts. Caesars Sportsbook is an entertainment product and we consider a variety of factors including account activity, integrity protocols, and consistency with our terms and conditions, when establishing wagering limits and determining VIP rewards and benefits. No decision is made solely on a customer's win-loss record.”
