About the VPN thing, you can literally get a specialized IP if you want from a private VPN, it costs money but they will do a unique one for you and if you get banned or something you can pay for another one and they will create another unique one for you, simple as that. Using that method you can go around doing whatever you want without a fear of getting banned. Seriously illegal, but they do it anyway.
That is a bit tricky isn't it? I mean they allow you to actually use VPN and even encourage it, they have that post about which VPN is the best, have absolutely no rules against it and when it comes to KYC you are screwed. So, how is that helping? Stake doesn't make it illegal to gamble on VPN but when you are asked for your KYC and turn out to be somewhere totally different... would they still pay you?
Since vpn is not illegal that sounds like they might still pay you because you CAN do it and its allowed and not in the rules so I suppose you should be allowed, but if it is not allowed, doesn't that make it de facto against the rules, if it is then why not put it in the rules to make it more clear as well? Maybe someone from stake could clear things up a bit.
