That is the thing that rings true. How many times have we heard about casinos freezing accounts of all associated multiple accounts before sums were deposited or just when accounts were created and sums deposited?
I commend Sportsbet for returning deposits to those that breached its ToS and I equally commend them for taking a strong against those that won on their website by breaching their ToS even if tiny amounts were involved because it is a matter of principle.
The only thing I see they have gone wrong in is when they clearly do not clamp down on multiple accounts until one of those multiple accounts tries to withdraw or wins and that clearly in unacceptable because it means Sportsbet can and will keep those funds without notifying the multiple account operators they have been caught - they seem to wait until the multiple account operators win before declaring a breach of ToS.
@Sportsbet - is there any chance you could ask the people making decisions at Sportsbet if they could look in to this please? If implemented it will put all future similar allegations against Sportsbet to rest.
There is a high probability that Sportsbet would have kept quiet and took no action if the OP had lost funds and kept losing them but took action after he won or tried to withdraw won funds BUT there is no proof that would have happened.
Perhaps on some rare occasions where casino decide to go trough accounts of all customers but usually it is withdraw button which triggers fraud team, who knows...
I still stand by "if you accepted bet, pay what you own and then block account(s) if you want to".
