Age-verification methods

Not just whether a site checks your age, but how: the verification vendor detected on the page, and the jurisdictions where we measured it serving an age wall. As laws spread, this is the ground truth of who is actually enforcing them and with what tool.

Vendor detected by rendering the page (specific vendor domains only); jurisdictions from our active availability probes. “Own age-gate” means an age wall with no third-party vendor found.
