Donating option not available

So I would like to donate using a burger king gift card because that seems like the only one I can use PayPal to buy with, but when I click Buy Coins, it takes me to the PaymentWall and asks me to choose what card I would like to use to purchase it. However, Burger King is not one of the options. It would be much easier if I can just use PayPal to donate to the server.

Than you can't do it with burger king card :/

these are subject to a region lock, you might have to use an (american) vpn
