I hope the wink doesn't mean "at your own risk" I hope those who decide to use it won't later get banned for this.
Also, what's the reason for blacklisting certain countries if you allow people from these countries as long as they use VPN? Wouldn't it be easier for you not to restrict them at all?

You could add a list of countries that are allowed in, because I'm not allowed (UK) and I could try it out with VPN, but I'd have to choose a country first. Making a list of restricted countries would make things easier for people who want to visit your site.
