No, nothing is blocked from my account. In fact, from what I can find about the topic, I think the ability to block certain currency types and countries is only available as an option for Premiere accounts and I do not have such a thing and can find no option in my settings, so I would not be able to block even if I wanted.
Though, I am linked through Itch.io for my Paypal, so maybe something to do with Itch is causing the issue? Might want to send something to Itch support and ask the same questions. Maybe the Itch Paypal configuration is contributing to the problem.
