Meta Deploys Multi-Modal AI to Catch Underage Users Across Posts and Visual Cues

Meta announced strengthened age verification on 5 May, deploying an "adult classifier" that analyzes posts, comments, and physical characteristics including height and bone structure to estimate user age. The proprietary system avoids facial recognition while attempting to triangulate age across behavioral and visual data points. The expansion follows earlier tests of video selfie-based age estimation and signals Meta's shift toward comprehensive multi-signal detection as regulatory pressure intensifies under the UK Online Safety Act 2023.
