Completely irrelevant!

First, a lot of casinos are partners with different companies to take care of the KYC process, Veriff, Idenfy, Netverify and many others, so if an established casino migrates to a newer KYC check service, how would you even quantify this?

Actually, I would rather be a bit concerned if the casino is doing those checks on themselves, how are they even doing this in the first place?
