I re-read the thread and the complaint on AG, and I think [based on the narrative so far] BC made a questionable decision. They initially voided the bet under an argument that it's an incorrect odds being displayed [after they previously asked OP to intentionally lose the bets to "void" his winning], but later revise it to OP exploiting unfavorable odds.
As far as I know, they're two different situation. When an incorrect odds being displayed, it would means the sportsbook shows a wrong numbers than what's intended to be placed/shown, but when someone "exploiting unfavorable odds", it means they have a knowledge [or perhaps simply a gut feeling] that a bet is quite likely leaning toward a predictable outcome. The former is a technical error, while the later can be considered [though sometimes not necessarily] as a manipulation by the player.
Unless I am mistaken, they're not interchangable. How BC.game can switch their decision from the former to the later is... interesting.
Should the flag be supported? Given OP tried to reopen the case, I think it's best to wait for the result of this request and the outcome reached.
Askgamblers said I cannot re-open the case. So all there is left to to is warn other for the unfair practices of BC.game.
I would appreciate if you could support the flag but it's up to you.
