You may be right but let us wait to see what happens when a Sportsbet representative gets in contact with you to address the issues you raised. I hope you post here and update us.
The biggest problem is operators hold the cards and they are happy to watch players lose but only enforce barriers when a player is winning. Had I been winning I truly believe it would have been a very different situation in that they would have flagged my accounts. Obviously that is not the case however so it's not a line of defence.
I am very interested to see sportsbet.io's take on this now that this case is public. I look forward to their reply.
