Depends on the level of KYC you are into like level 1 is very normal and this can be faked out by members but if you are playing on the casino then avoid these things and play genuinely as if caught your account could be freezed and funds will be locked so try to be original and follow the rules while gambling.
I prefer to use original document both on gambling site (sportsbook as well as casino) as well as crypto exchange site. Casue if I use any fake info that might be used by someone else too. If that happens then the account of mine can be locked due to the use of fake document. And I not only use the real document but also I suggest everyone to use real document.
