Can't, as you need you a legal address and paypal with a legal address for patreon and subscribestar to be allowed, using a VPN won't change the addressIs it so difficult to buy a VPN? Lol
To leave the country because of the development of some game for which you haven’t really gathered support - such nonsense!
All I know is, that the dev, found a way to be able to add patreon and subscribestar as a option which means they need to move a way for a while, it could be, that they are going to a family member outside of Russia and when, it's all set up, they can return home
