In cases where the casino may get hacked and kyc documents stolen, in most cases, we can't completely put all the blame them because believe it or not, every business sometimes go through issues no matter the type of issue.
As long as the casinos follow the proper data protection measures required by regulators, they can’t be blamed. But if they don’t, then they should face complaints and possible lawsuits. This is part of the risk we take when entrusting them with our data through KYC requirements. To minimize that risk, we have to be selective in choosing the right casino to play with, and that is to stick to reputable ones, as they usually have stronger security measures in place.
