Ask HN: How do you prevent users from certain countries from using your web app?
How will you screen for and prevent people in comprehensively sanctioned jurisdictions, namely Cuba, North Korea, Syria, the Crimea region of Ukraine, or Iran from using your app?
My typical answer is ...
Our app is only available to people who have a Gmail or Facebook or Github or Twitter account. We believe Gmail/Facebook/Github/Twitter accounts are not available in the above countries. So we cannot have customers from these countries.
Their reply goes ...
Thank you. We will update you in a few business days, or possibly up to a week due to a surge in interest.
And then it's back to the same question ... how will you prevent people from certain countries from using your app? This has been going on for two months now.
