Ofcom has opened a formal investigation into whether TikTok's age-inference systems adequately protect children from harmful content under the UK Online Safety Act, marking the shift from rule-making to enforcement. The probe will test whether behavioural age estimation meets the statutory threshold of being 'highly effective', with potential fines up to £18m or 10% of global revenue if breaches are found.

◆ ◆ The Wire takeaway
If Ofcom rules that behavioural age estimation is insufficient, every platform will face pressure to deploy stronger age verification—which means buying from identity and age-tech vendors or building in-house at scale. This is the first major enforcement test; the outcome sets the bar for Europe.
