However, in terms of risk, its not on the casino because as long as the gamblers are losing, they're welcome all the time.
If this is harmless and poses no risk to the casino, then why do casinos always find ways or if they find out players are circumventing the rules, continue to ban them?
I think it depends, as if it is a registered casino and is strictly regulated by law enforcement. They need to be strict about this, they can't just go after small profits and may pay a heavy price if law enforcement finds out they are being lax in managing their users. Casinos also have risks and that is why they are very strict about this although it cannot be completely prevented as players will have many ways to cheat, IMO.
It would be a huge mistake if the casino ignored this, but I’m sure they’re well aware of the risks. That’s why they enforce strict KYC checks before allowing withdrawals—not just because it’s legally required but also to protect their reputation, as it prevents the platform from being misused for illegal transactions.
While they can’t catch everyone, this approach definitely reduces the chances of shady activity. So, for those gamblers who don’t like the KYC process, well, they’re probably the ones most likely to try to cheat the system! Because I see the huge benefits we can get from doing this, not just for the casino but also for us players.
