4chan: age checks in the UK

No active age check was found as of 18 October 2026. 4chan’s Rules page (read 18 October 2026), Global Rules: “You will immediately cease and not continue to access the site if you are under the age of 18.” 4chan’s FAQ: “In order to access the full site, you must first read and agree to the terms of the disclaimer. To access the disclaimer simply click any board and a dialogue will appear. Your response will be cookied so you'll only need to do this once (providing you don't clear your cache/cookies afterwards).” Posting needs no account: “No user registration process is available.” and “In order to post on 4chan you have to do one of the following: If you are a new user of 4chan (i.e., have never posted before), simply wait for 15 minutes before attempting to post. … Verify your email address to be able to post immediately. Have a 4chan Pass.” None of the three pages describes a check of a visitor’s age, names an age-assurance provider or mentions the United Kingdom, Ofcom or the Online Safety Act; the rules, FAQ and legal pages were served to a UK visitor without any age prompt (the boards themselves were not opened). Ofcom’s investigation page (last updated 21 April 2026): “Ofcom has determined that 4chan has failed to comply with its duty under section 12 of the Act to ensure that children are prevented from encountering pornographic content on 4chan.org through the use of highly effective age assurance, and that this failure is ongoing.” Ofcom’s confirmation decision of 19 March 2026 required 4chan “to implement highly effective age assurance on 4chan.org by 2 April 2026” with “an additional daily rate penalty of £500 per day … until the date section 12 is complied with, or (if sooner) by 1 June 2026”. Ofcom’s June 2026 industry bulletin: 4chan fined “a total of £540,000 … (with daily penalties of up to £800 until compliance deadlines are met). Further enforcement action may follow should non-compliance continue.” No Ofcom page read after June 2026 records whether 4chan has since introduced a check.

Ofcom, 10 June 2025: Investigation opened into whether 4chan failed to respond to a statutory information request (sent 14 April 2025 asking for its illegal content risk assessment), to complete and keep a record of that assessment, and to comply with the illegal content safety duties. Case reference CW/01307/06/25. Ofcom, 13 August 2025: Provisional notice of contravention: reasonable grounds for believing 4chan contravened its duty under section 102(8) to comply with two requests for information. Ofcom, 13 October 2025: Confirmation decision: 4chan “has breached its duty under section 102(8)(a) of the Act to comply with a statutory request for information, on two separate occasions”; fixed penalty of £20,000 and a daily penalty of £100 for up to 60 days until the risk-assessment record and revenue information were provided. 4chan had until 13 November 2025 to pay. (£20,000) Ofcom, 4 December 2025: Scope expanded: Ofcom added whether 4chan “has failed, or is failing, to comply with its duties under section 12 of the Act” to use highly effective age verification or age estimation to prevent children encountering pornographic content. Ofcom, 12 February 2026: Provisional notice of contravention covering the illegal content risk assessment duty, the terms of service duties and “its duty to protect children from encountering pornographic content through the use of highly effective age assurance”; 10 working days to make representations. Ofcom, 19 March 2026: Confirmation decision under section 132: £450,000 for failing to use highly effective age assurance (section 12), £50,000 for failing to carry out a suitable and sufficient illegal content risk assessment (section 9(2)) and £20,000 for not specifying in its terms of service how individuals are protected from illegal content (section 10(5)); each with a 2 April 2026 compliance deadline and daily penalties of £500, £200 and £100 after it, running at most to 1 June 2026. Case closed on this date; the non-confidential decision was published on 21 April 2026. (£520,000) Ofcom’s confirmation decision of 19 March 2026 required 4chan “to implement highly effective age assurance on 4chan.org by 2 April 2026” with “an additional daily rate penalty of £500 per day … until the date section 12 is complied with, or (if sooner) by 1 June 2026”.
