The UK government has announced a default curfew restricting social media access for 16- and 17-year-olds between midnight and 6 a.m., extendable from prior under-16 measures and including defaults disabling auto-play and infinite scroll. The curfew can be overridden via account settings, with rollout timelines disputed across sources. Critics including the Molly Rose Foundation and Laura Trott have described the approach as piecemeal.
