Reasons ranged from "not in the spirit of the promo" to claiming balances with more than one of the many Sportsbook.com name brands was taking advantage. This was despite the brands' marketing teams were targeting each other's players offering bonuses and there being no rules against it. Shortly after they picked an arbitrary time period and confiscated winnings from correlated parlay winners (which the software allowed) and let the losers stand. Had you won 100k during their 4 month period and lost 110k the month before they still took your 100k.
There is a legendary story of player who won a 10 team parlay about 8 years ago now. The whole office was following it. He won 700k and then, by refreshingthe page, watched them change the rules page to show max parlays payouts at 400k. Employees from that period will remember it. The player claimed the clerks acknowledged it on the phone. That sums them up. Sensitive enough to the brand not to stiff regularly but they aren't going to let a winner or two mess up their quarterly figures.
We really can't argue with victims who say they should be an F rated book. The D range better shows the actual risk level for normal players.
