Which one have a purpose to being anonymous? Roobet never wrote anything that their casino is an anonymous and never collect any KYC from their users, Satoshi a creator of Bitcoin, never wrote Bitcoin is an anonymous, but it's pseudonymous. If you talk about Monero and other privacy coins, you're collect since their purpose are being anonymous currency. But most of casinos didn't accept it due to anonymous and harder to trace the transactions, origin etc.
I think we should stop discussing about KYC on Roobet.
If they change their Terms of Service, announce it transparently and give users time to withdraw money if they don't want KYC, it is very good. Nothing to discuss that Roobet does a bad thing and discussion like that is not true.
Bad things only for situations when you change ToS secretly and don't allow users to exit your platform if they reject to KYC. It is not what Roobet team did so it is all fine from their side and user side.
