What countries are not supported by MoonPay?

I'm interested in using MoonPay for cryptocurrency transactions, but I'm curious about which countries are not supported by the service. Could you please provide a list of the countries where MoonPay is not available? Additionally, could you explain the reasons why these countries are not supported? I'd appreciate it if you could provide a brief overview of the geographical restrictions and any potential alternatives for users in these unsupported countries. Thank you for your help.
