TikTok refuses to serve age-restricted or sensitivity-flagged posts to an unauthenticated client. In --flat-playlist enumeration they drop out of the list with no error at the collection level. Gating can be applied after a video was first fetched. The loss is biased by topic, since health-adjacent content is the class that gets flagged.
