Has your friend got the cashout already? And now the only complaint is about locked account with no balance? Or the cashout is still pending?
most people bet in round numbers like a $10, $50, $200 bets etc...
but if you are actually doing arbitrage with a calculator to maximize your profit, your bets would look like something like $22.5, $134.7, etc... which is a dead giveaway.
even if you round your bets to have no decimal points, it's still easy to detect since normal players don't bet like that.
Thanks for providing such valuable insight, next time I will make sure to pay attention to my betting amount

Of course so that they can't accuse me of something I did not do

Joke aside, basically if are a smart gambler, you are not welcomed lol.
