Ok, suddenly the casino you're playing asks you for proof of income to be able to withdraw your winnings and to keep your account in good standing, your bankroll every month is $500 and you provide proof of salary that you are making $500 net every month, will they accept that proof will they accept that you are putting all your salary for gambling, will this violate the principle of gamble for fun, because you are working to gamble based on your proof income.
i will skip gambling sites that force me to do this, for me it is very annoying if a gambling site requires me to give them my salary slip every month just so that i can play and make withdrawals there. remember that you are gambling with your own money, so use it as you please, even spending it is your own right.
It's great to get past gambling sites that ask you to send proof of your salary because that is your privacy. If that happens to you, you have the right to move to another casino, and casinos cannot impose their rules on gamblers. But usually, if we have won a lot of money and want to withdraw, the new casino will ask us to do KYC and even ask for other requirements to complete, such as proof of salary. So it will depend on each gambler, and we can choose before deciding.
