Meta will use AI to analyze height and bone structure to identify if users are underage

Meta will use AI to analyze height and bone structure to identify underage users; the system runs in select countries. The post does not disclose countries, error rates, or appeals.

Why it matters: HKR-H comes from the biometric age-detection hook; HKR-K has a concrete mechanism; HKR-R hits privacy and child-safety concerns. Missing countries, false-positive rate, and appeals keep it in the low featured band.
