that is probably it. it gives you a fake IP for the server, that exits to the real server from a "good" location
or actually nvm, another way this could work is a *transparent* TLS proxy so it's basically VPN-lite

No, you lost it again 😂
Verification services are mostly contracted external services.
NextDNS simply blocks the verification site and returns a "I've passed my age verification test" back to the target site.
This is why it only works when sites sub-contract their age verification service, which tbf, most do.
