i used to play on stake.com with vpn it worked
Oh, really??? That must have been luck played in your favour. Casinos frown so much on the use of VPNs and even if you are gambling with one account, some VPNs would put you in trouble and your casino might think you are using multiple accounts since the IPs might be matching with other gamblers' IPs elsewhere. This is why VPN is so discouraging to use especially if it is the free or cheap ones. Yours might be the uncommon or new VPN with solid strength and reliability. I still urge you to rethink this before it costs you. Nothing is better than using one's local IP with casinos.
But if you look at it from the player's perspective, they think differently. Some people prefer VPN or privacy focused browsers like brave or mullvad which have VPN built in, not because they want to cheat but because they want to protect their privacy. And I don't see anything wrong with them protecting their privacy because as we all know how dangerous the online world is. So I don't think it's fair that casinos don't allow or don't want you to use a VPN.
Personally, I like to use VPN all the time not just for gambling and I feel safer doing so. By the way, I just tried accessing stake with VPN and I don't see any problem, I don't think they ban players from using VPN.
