Well when you joined then the situation of the site was different but once the implemented the KYC thing and added it into their terms and conditions then that's the thing you must have to keep in your mind. Most of the casinos require some kind of KYC these days and I'm quite sure that no good casino is allowing members to get withdrawals of good amounts without completing the KYC details.

It's a policy from those casinos and if they asked you about KYC details then you'll have to provide those details to them and once they get those details then they will verify your account and release your funds. It's really something against a user's privacy but we can't do anything because it's now a days in terms and conditions of almost every trusted casino. If you really want to access your account once again and withdraw your funds from their platform then you must have to send them those KYC requirements.
