Can't they make an adjustment to this rules as I know more people wouldn't find this part interesting to continue using site, as this could be the reason for Dr. Osh account closure, but however even though he deletes his account the details still remains within the system so he it's not entirely gotten rid off from the their system.
I’m not sure if customer support will grant his request and make an exception for him, to be honest. They are bound by regulations to keep the collected data in case it is needed by the relevant authorities.
I hope they will, but it would be interesting if they do, as it means that they don’t mind breaching their own policies which may result in legal consequences.
The good thing is that after account closure, those data will remain confidential and they will not share it with third-party entities, except when requested by the relevant authorities.
I have actually not come across any centralized services which includes casinos that will delete your account upon your requests and completely erase your information and data from their system.
When you request that your account be deleted and that your personal data be completely wiped off or erased from their the casinos system for life, they customer support or the management of that casino may tell you or inform you that your request has been granted and that everything about you has been erased, it's simply a lie, they tell you this to simply avoid long talks.
Just as you have right said, they will and must keep a part of the users personally information for any important use of it in the future if or when the need arises, I guess this is the reason why so many people who understand perfectly how this systems work are always afraid and or against kyc services, like casinos where kyc verification is mandatory.
