Figures from digital data company show effect of strict rules brought in last month under Online Safety Act

British visits to popular pornography sites have slumped following the introduction of strict age checks last month, data shows.

Daily visits to Pornhub, the UK’s most used porn site, fell from 3.6m on 24 July, the day before age-gating was introduced, to 1.9m on 8 August, a drop of 47%.

At the next most popular sites, XVideos and xHamster, visits fell 47% and 39% over the same period, according to the data from Similarweb, a digital market intelligence company.

The data, first reported by the Financial Times, appears to show the impact of strict age-checking rules from 25 July under the Online Safety Act. However, social media sites that also introduced age checks for material barred to under-18s, such as X and Reddit, did not experience dips in traffic over the same timeframe.
