If we choose a trust and have reputable casino, they will take care our document carefully and will not do something illegal with that. They will serves us better by always secure the document because they know that trust is the important thing for their customer. User can not do anything except follow the rules but they have choice not to do KYC if they don't like. If that so, user don't have to play gambling at that casino and search for the casino that don't have a too strict rules. But in the future, we don't know which casino that can be like that.
Not everything will be like that because there are careless people who dare to complete the KYC process on gambling sites that do not yet have reputation and are not popular like novice gambler, they do not understand the risks, and for gambling sites that clearly have good reputation, it is not problem when it comes to completing KYC.
Every gambling sites that has grown rapidly and become one of the best gambling sites must have team that will protect all customer data when they apply KYC requests, as gambler it is better to follow the rules and try to continue to fulfill all requests in order to be able to bet more comfortably.
