I agree it's going to get tricky. I'm also in a region that enforces age verification, so I'll have to use a VPN to access my own platform!
It's a difficult trade off between privacy and ease of access. I want to make it as easy as possible for people to use the platform, but I don't feel right about being complicit in asking users to upload a photo of their ID to a private company somewhere in the US.
Blocking regions that require it definitely isn't the final solution, and it's something I'll continue to search for a better solution to that doesn't compromise on privacy. But at least for now, it's looking like using a VPN is the safest bet.
