It can be found if we can look for it carefully because with so many casinos nowadays, not all casinos will allow gamblers not to do KYC. Casinos today are different than they were a few years ago, and with government interference, they have to keep up if they want to continue doing business. And if we have found a casino that really can be trusted, we should also be able to be calm about doing KYC because the casino will try to protect the important data of its customers.
Most of the casinos do look at what country you are from and base their regulations on their judgment as to whether they will require you to undergo KYC or not. I have friends who are into sports betting or gambling in casinos, but they are not required to go through KYC, just like me. Therefore, we enjoy the full liberty of gambling anonymously.
But you should not forget to check their ToS in terms of KYC requirements.
Even if they are not requiring you to submit one, you need to remind yourself that if it is stated on their terms,
you should always prepare your KYC docs, and should correspond to the details you entered to the site to avoid trouble.
We can't be so sure that these casinos won't ask KYC from you. They can easily do random checks and ask your credentials.
Checking the Tos to get familiar with the KYC requirement and how the casino handles kyc data make more sense than practically neglecting the to and there after blame the casino if you kyc data never get approved or not, but once you get verification for the submitted documents, the security of the data provided is now left in the hands of the casino and how the store those data becomes their responsibility most time we are unaware of what happen to those data afterwards but we trust the casino to protect our privacy as much as possible.
