TOR might be the solution besides a VPN because users have to buy a VPN to get full access from the premium VPN. Besides that, using a free VPN to connect to the internet is not recommended. I don't know if the government can sanction internet provider companies but maybe they can do it because they are the regulators of our country. When you use a VPN or TOR, you can hide your real location so that it can protect you from unwanted attacks. Nowadays, KYC has started to be implemented in many casinos even though they impose requirements for their members to complete KYC.
TOR bowser become another solution when sportsbook and gambling casino block or banned in some countries, I don't think which one most safety access by using TOR browser or VPN when get banned on website gambling. Not seeing about VPN premium or free but I care how safety our account when access using TOR browser or VPN, both way are using IP from another country and sportsbook or casino gambling site detected access of our account from different IP address. Some sportsbook have different domain id and better to check if general domain was banned need to find alternative domain but keep on the same website of sportsbook.
But when your country prohibits gambling, even if you use the TOR browser or VPN, free or paid, it is very risky because, after all, you have violated the rules in your country. It's just a matter of time until the regulator in your country identifies you because you are gambling, even if you use TOR or a VPN. In addition, we also need to look at the list of countries that are banned by sportsbook sites and gambling casinos because we don't want to break the rules from them. Sportsbooks and gambling casinos have different domains to avoid blocking from the government but don't gamble if your country forbids it.
