Perhaps we need a thread to discuss whether a casino should allow VPNs or not since the thread rarely touches the title or OP's intention of sharing VPN-friendly casinos or good VPNs for online casinos recently. Or OP can change the title to expand the discussion?
I think this is the case now simply because now AI can easily figure out all the VPN servers and those large businesses (such as banks that support banking applications) have VPN control tools. And it becomes almost impossible to hide it.
Where do you get that info from? I've never heard of advanced filtering tools using AI to detect VPN IPs. Then again it doesn't take a long time to build a script and a filter as long as you have the database of IPs used by VPNs. I'm pretty sure all of them don't matter if you simply visit a VPN-friendly casino though. Maybe if you use cheap/free VPNs so your IP is regularly used by bots that will be a problem. If you buy a good VPN or s dedicated IP the chance should be low (as long as the casino is not planning to screw you themselves). CMIIW.
If we talk in general about the structure of information exchange on the Internet, then I would divide all Internet Services that work with clients, both paid and free, no matter what, into three large groups: first, these are Services that generally receive and respond to requests from any IP outside depending on whether it is suspected to be a VPN server. The second group is those Services that filter requests for those from VPN and direct ones from personal IPs or reliably known IP addresses. But these Services pass and process requests and at the same time know whether the client is using a VPN. And the third group of Services simply blocks the exchange of requests via VPN. This group usually includes serious banking applications where KYC must be automatically completed. So, most of these Services naturally know VPN servers that are free and paid, and even dynamically appearing and disappearing. It is for such complex VPN presence identification that AI is used. Naturally, few users have heard of such traffic filtering methods, since none of the specialists is interested in talking about the specific details of such identifications.
In my opinion, almost all casinos belong to the second group, since the presence of a VPN gives them another prohibitive argument in the process of paying clients the money they have won.
And sometimes it even helps not to pay the client winnings and can even save money on this for the casino.
