I am not worried about data theft at reputable casinos, I think the data is safe and confidential. But doing KYC is less of a hassle for me. It annoys me when they reject the data as incomplete and ask me to re-enter it. It is very annoying for me. So I try to avoid KYC as much as possible, not that I am afraid of data theft.
Since I am an irregular gambler and gamble very rarely, I do not have much reason to worry about it. But going through KYC for any account seems annoying to me, even when I am opening a CEX account.
If you think that your private information is safe with them, following information could change your kind, as there was recent incident where billions of personal records linked to the company called IDMERIT leaked recently.
An unsecured database linked to IDMerit exposed one billion personal records across 26 countries.
Leaked data includes national IDs, full names, addresses, phone numbers, and potential telecom metadata.

Who would be responsible when (not if) personal data gets used for criminal activity or he falls to some scam in which hix personal data is used? Should the company that "safely stored" his personsl data become held responsible? Or maybe regulators who forced KYC policies in the first place?
Storing large amount of KYC data is just ticking time bomb, there is no question if the leak will happen, it is just matter of time when will it happen.
