By the way Holydarkness, providers indeeds is the one flagging for whatever (arbitrage, value betting etc) but they never void the bets. The bets remain unvoid and shown as won in cases like this. The fact that the sportsbook (in this case XYes) then only pays back the deposit, means they put the voided winnings completely in their own pockets. The provider does not get these funds, as far as they know the bets are still won and paid.
