There’s no need for that. The casino already claimed that the OP has other accounts and even asked them to provide a list, implying there’s more than one, since it’s called a list. Also, I don’t think Rollbit would reveal the accounts or IPs used, as that would likely violate privacy laws, and they could face penalties for doing so. That’s why having a mediator is crucial in this kind of situation.
I think what he meant is if there’s no questionable bet that gives him advantage through multiple account such as arbitrage betting then there’s nothing wrong of having multiple account.
I’m not familiar with Rollbit ToS however multiple account shouldn’t be a big deal of there’s no abuse on his end or circumventions on any restrictions.
But we all know Rollbit will not flagged an account for multiple account if nothing is wrong. So it will really help if betting history will be available.
It’s tough to win an argument against a casino because they can always claim something that we, as outsiders, can’t verify. Maybe OP can try to prove their case, but even if all the bets are posted here and we’re convinced they weren’t cheating, the casino could still say that OP didn’t post everything. Then what? Which side would we believe?
And can we force the casino to present their evidence here? The answer is no, that would violate privacy rules. Unless this issue is brought to a proper venue where both parties are required to cooperate, it’s unlikely to be resolved. Both sides need to work together to reach a fair outcome.
