I only pointed out that the casino's refusal to ask the client to verify his account is bad form and should lower the casino's rating very much!
And I see no reason for it. Apart from that, no reputable casino will refuse your documents because there are thousands of accounts from your country using the same documents. Unless you are trying to deceive, by using forged documents just avoid any future trouble.
My message on this forum is to convey from inexperienced community members how the casino cheats them even before the game starts! So if the client wants to get verification before the game starts, then the casino is obliged to do it! If the casino refuses, then this should lower the casino's rating!
Same bs. Therefore, if you see that a bookmaker confiscates a client's winnings based on arbitrage bets, you must clearly understand - this bookmaker is engaged in fraud!
It is good that most of us don't have your level of clarity 
What if a bookmaker accuses me of arbitration and confiscates my money, and in response I send him a lawsuit with evidence that each of my bets was 100% not arbitration!!! How to prove this?
Arbitrage opportunities are very rare and can be easily narrowed down by bet providers. No reputable casino is built upon malpractice; it is simply not sustainable.
