There is a way to protect your privacy should something like this happen - by requesting the cancellation of your old documents and the issuance of new ones. That naturally comes at a price, but it can be done. What's a little more difficult is changing your address or name, but there are people who will do that if they feel threatened.
There are ways to do that but these methods are only helpful for you in your homeland. I am not quite sure that if you request a new identity card, a new passport from your government, and consequently previous one will be cancelled and become invalid, these leaked documents will still be able to use by other people.
They can do things like using such identity documents for opening and verifying accounts on centralized exchanges. You can not control that and exchanges will possibly approve those registrations and KYC with your old documents. Exception is if you already had accounts on those exchanges, and exchanges detect overlap among documents and refuse later accounts use your documents, even old version.
The key thing is that you should not trust anyone when it comes to your documents, especially private companies like Revolut or any CEX. Criminals are looking for every possible way to get hold of information about people who trade or own cryptocurrencies, and that is why it is necessary to start using decentralized services that do not require KYC.
I agree with you.
I know there is thing like Right to be forgotten, but as you said, we can not trust anyone, any entity about that. We can send a forgotten request, they approve that, but who knows what they do after sending an approval email to us.
