Sometimes VPN usage is seen as an illegal act, and even in my country, police get people arrested if they discover that you use vPN on their device and that is because VPN is mostly used by criminals who want to hide their location and identity, some times scammers are the users of the VPN but none the less, I don't think also that VPN users are all scammers because we still have some of the genuine VPN users who don't use it to commit any crime.
With regards of the usage of VPN Metawin has a clear stand about it which is stated in clause 18.1.8
18.1.8. You attempt to use your Customer Account through a VPN, proxy or similar service that masks or manipulates the identification of your real location, or by otherwise providing false or misleading information regarding your citizenship, location or place of residence, or by playing Games using the Platform through a third party or on behalf of a third party;
and is deemed fraudulent which is stated in clause 1.4 . If I am not mistaken, I understand the clause that using a VPN will result in an account ban.
1.4. Fraudulent Conduct– means any of the conduct described in clause 18.
So if someone doesn't want any future trouble while playing on Metawin, they better forget about using VPN on their gameplay.
