Isn't the official confirmation from the support party enough to provide certainty. If only to confirm through x officially just for the sake of satisfying one question then I think it will be difficult to materialize.
It's clear that Razed team already answered and confirmed about the mirror link that is officially from the casino.
If you still feel uncomfortable, just use the main domain, mirror domain for those who experience restrictions and cannot access the main domain.
Restrictions here need to be emphasized that they are restrictions from nations, locals, not from the casino itself. People who have such restrictions from their nations or local areas can use mirror site to use the Razed casino, and they will not have issues with Razed if their geographical locations are not restricted by Razed. But there is risk with their governments, and they must be aware about that risk as they will be fully responsible for any legal issue with their national governments or local councils.
