Question about donating (not why it's down)

Hi, a friend/guildie of mine is looking to donate but paysafecard is not an option in his payment portal, however it is for me.
This obviously has to do with where we are connecting from, so I came to think about VPN's.
My question here is, would it be allowed for him to connect to the homepage with a VPN for the sole purpose of getting other payment options aka paysafecard and then go back to not using a VPN? after all, who would prefer using VPN with the extra pings...

I'm looking this up for him since he mentioned paysafecard was not available to use as option here, but he can still buy them in his country and I remember when I donated, i saw paysafecard as an option.

Would love a respond to this from a mod or higher up so that my guildie does not donate and get banned for it or something like that.
