The amount they offered him (which he has until now refused) is the sum of his deposits minus his withdrawals. In effect he would be getting a full refund, and they would go about their business, quite literally. Somehow it's not ringing the "scam alarm" to me.
This is not my understanding. The OP placed bets with his deposit, that Sportsbet appeared to have accepted that turned out to be winning bets. The net winnings are excluded from what is being offered to the OP.
I understand that philosophy, but we don't know the whole story, and Sportsbet.io isn't obligated to disclose it. In fact, considering what it would take to prove their suspicions to us, they are very likely obligated NOT to disclose it.
What if the OP is from the US, or another probated location? Do you suggest they should break the law, and pay the winnings? We don't know what evidence they have, and I'm not trusting a bitter newbie over an established business.
I would be willing to give Sportsbet the benefit of the doubt that the OP was multi-accounting. It is not clear if this was an innocent mistake on the part of the OP (for example creating an account in 2017 when he wanted to bet on the outcome of a game, and forgetting about it), or if the multiple accounts the OP allegedly had actually caused Sportsbet some type of harm. This is why I posed the below questions above:
My question for Sportsbet is, what harm did the OP cause in his alleged multiple accounts? Was he receiving some kind of free bets he was not entitled to on some of the accounts? Was he placing opposing bets on the same game on two accounts?
I am also curious as to how Sportsbet is going to handle the OP's alternate accounts? They indicated above they will allow the OP to withdraw the difference between what he deposited and withdrew on the account he won the coin on. Did the OP's other alleged accounts have net losses, or net winnings? Will you allow the whoever has control of the OP's other alleged accounts withdraw the difference between the amount they deposited and withdrew?
I don't know the answers to the above questions, however if Sporsbet is dudecting net winnings, but not crediting net losses back to the OP's various accounts, it would not be a very good look.
As far as I am aware, Sportsbet has not articulated the harm the OP caused in having alledged multiple accounts.
