This is not going to be easy for us later although now, for those of us that do not like a KYC casinos because we don't want to share our credentials to casinos and of misused, our identities can be known by the public. We maybe be surprised that other casinos too might join this same trend especially for those ones that are KYC free.
When I heard there's a gambler don't want to gamble because of KYC reason, I feel it's completely bullshit. Even you're play in no KYC casino, the site already record your IP address, your device specification etc. Maybe you only gamble for small amount money and think, the casino will not ask your KYC, but when you win big amount of money and they ask your KYC, you will choose to give your KYC.
IP address can be changed with VPN and it's not an indicator of the person, just a router used to connect to the site. For instance, there's a lot of free wifi access points in restaurants and other places. There are shared IPs, like when you rent a room in a flat and there's 4 or 5 people using the same access point. Device specification? You mean the browser and system, or the MAC of your network card? Both of these things don't specify a user. They can be used to identify a computer, if that computer gets physically seized, but having this information doesn't allow anybody to identify you as the user.
I don't like KYC and I avoid it as much as I can, so for me forced KYC would be a reason to stop using that site.
