It's not rare if the platform was previously a fiat-only type of casino. Bookmakers such as bet365, bwin, William Hill, and others who deal exclusively with fiat require that their customers provide all their details upon signing up. If one of them were to adapt crypto, that probably wouldn't change. The same thing happened here. At least, it's been proven that the site is not a phishing site of the original domain, but I would still not trust them with my KYC details. If they want to create a healthy userbase on this forum, the KYC requirement has to go.
