If you grab a "bad line" on a sportsbook and when you select it and click "confirm" it gets "referred to trader" and then the trader still confirms it, can they still void the bet after it happens? They still haven't voided the bet but think they might be waiting till after the result. Then if the pick wins they will just void it and give stake back or if the play made loses they will pretend that they wouldnt of voided it and just take the money - that way it is win-win for them. Surely there is a rule that they can't do this? Surely a book has to void the line before the event takes place as otherwise they could always leave "bad lines" out there, then let people grab them, then just wait till after the event and decide whether to void or not depending on whether the result suits them or not?
