Hey Johnny!
I really appreciate your desire to help support this instance- seriously, it means a lot. Erring on the side of caution is reasonable and I don’t blame you.
I’ll be honest, I don’t have an immediate answer for privacy conscious payment methods for US users, but give me 2-3 days and I will find out what method works best for you. Again, it’s awesome you posted this so we can figure it out not just for you but for other privacy focused users based in the US.
Thanks for bringing this to my attention!
