Sportsbook.com (SBR rating D+) confiscates winnings made from correlated parlay bets dating back over one month. SBR is currently investigating complaints submitted by four players who were informed via email that thousands would be deducted from their balances because winnings derived from parlays where the legs of the parlay are "linked." Wagering on Over the total score and the Underdog spread would be an example of a correlated 2-team parlay. Some sportsbooks use their software to prohibit these types of wagers. SBR is also investigating a separate claim made by a player who states that over $80,000 was confiscated because he utlized different sportsbook websites within the Sportsbook.com family (Jazette ltd Group) of sportsbooks. This has been allowed and often encouraged by the different brands in the past. SBR will list updates for all Sportsbook.com complaints ranging from instances of incorrectly graded wagers to missing balances from sportsbook brands that defected from the Sportsbook.com operation to other white label services.
