I understand what you are trying to say . but Imagine if Stake Paid him his deposit Back . Like Ok Man you tried to Scam Us and Book on a Rigged Market We catched you so here your deposit back and will Void the bet . (It will be like a slap in the wrist ) and encourage all other shady bettors to try to do the same risk free if they caught they lose nothing if they not caught they cashout.
you should understand from the point of view of a huge business and bookie like Stake .
based from the news i read it was some American Bookie who raised red flags about that Betting line and there was a huge flow of money from a lthousands of accounts(since there bet limits) so who knows if the OP was one of those accounts?
Iwould say for the OP you are lucky you are not in the US right now and you didnt Use a US Bookie . they dont play games in there you would end up being investigated by the FBI
add to it the Shohei Ohtani and his his translator Scandal last month they are serious about investigating such things.
It's not what you said above, you said that even if he bet on a rigged game by pure chance, he should accept the decision and move on, because the case is already over according to you, while it would have nothing to do with trying to scam anyone. Now you claim he's a cheater and he deserves to lose its deposit, it's not the same thing at all. If he didn't cheat it's none of his business how the casino manages cheaters and tries to affraid them, and he shouldn't lose $45k because casino business politics.
