What's the canonical way to block users from age-gate jurisdictions to one's website? I wish Cloudflare had a wizard flow for this. I'm not going to age-gate access to my blog (it's a wiki so it has user-generated content) so I'd rather jurisdiction-gate it.

Perhaps we should have network traffic report its geographic location so that we can comply easily. Would prefer something in an IP packet so that I can just filter at the firewall. Doesn't even need to be implemented in a sophisticated way at clients. Can just have the urgent flag repurposed to mean "respond only if not geo-locked and unconcerned with regulatory" and then I can drop these directly, and regulated source locations could ensure that packet flags are correctly set at the widest peering location out of the UK and so on.
