How are you going to prove arbitrage? You found my 2nd account where I allegedly got an advantage? I don't understand you, you are too confident and you have fake evidence, why didn't you show it? Are you afraid to screw up again like your casino?
I don't have to prove anything, mate. Why don't you understand a single thing that the casino does not flag the account for arbitrage betting, but the odds provider (in this case, the provider is BetBy) flags the arbitrage bet and informs the casino to freeze the account? In your case, Betby reported to the Xyes and informed them about your bet, and the casino has nothing to do except for blocking your account.
In your case, the casino refunded your initial deposit and forfeited the winnings. I was in the chat where they provided the proof to another forum member, and I guess he is gathering more information before he comes back to the forum. So, be patient.
