13 October 2025Ofcom monitoring services which take steps to stop UK users from accessing them

In recent enforcement activity under the Online Safety Act, Ofcom has prompted several online services to restrict UK access as an interim risk-mitigation measure. Rather than implementing the safety measures required by Ofcom’s Codes, a number of providers have opted to geoblock UK IP addresses, materially reducing the likelihood of UK users encountering illegal or harmful content. Ofcom concluded investigations into four file-sharing services under its CSAM enforcement programme - Krakenfiles, Nippydrive, Nippyshare and Nippyspace - after they implemented geoblocking for UK users. These cases were closed on the basis of the reduced exposure risk. Ofcom will continue to monitor the availability of these services in the UK and may re-open investigations if circumstances warrant it. Investigations into two other file-sharing services, Nippybox and Yolobit, remain ongoing.

Separately, Ofcom’s first investigation under the Online Safety Act into an online suicide forum led the service to implement a UK geoblock. After further engagement, the service removed landing-page messaging that previously encouraged UK users to circumvent the restrictions. Ofcom has made clear that any service choosing to block UK access must not promote or facilitate avoidance of those measures. The forum will remain on Ofcom’s watchlist, and the investigation will stay open while Ofcom verifies that the block is maintained and that the service does not direct UK users to bypass it.

13 October 2025Ofcom clamping down on providers that ignore legally-binding information requests

Ofcom has fined the operator of 4chan £20,000 for failing to respond to two formal information requests under the Online Safety Act: one seeking its illegal harms risk assessment and another related to its qualifying worldwide revenue. In addition to the fine, a daily penalty of £100 will be applied from 14 October 2025 for up to 60 days or until the information is provided, whichever is sooner.

Provisional decisions have also been issued against file-sharing platform Im.ge and adult content provider AVS Group Ltd for similar failures to comply with information requests. Ofcom has further provisionally found that AVS is not meeting its legal duty to implement highly effective age verification to prevent children from accessing pornography. Ofcom has also expanded its investigation into Youngtek Solutions Ltd to assess whether it adequately responded to a statutory request regarding its age assurance measures.

13 October 2025 - File-sharing services now using automated tech to tackle CSAM following Ofcom enforcement

Ofcom has confirmed that file-sharing platforms 1Fichier.com and Gofile.io have implemented perceptual hash-matching technology to detect and remove child sexual abuse material (CSAM), following serious compliance concerns identified earlier this year. The enforcement action was part of Ofcom’s ongoing programme to assess how such file-sharing services, which can be exploited to distribute CSAM, are meeting their duties under the Online Safety Act 2023.

Both providers engaged with Ofcom and committed to strengthening their protections in line with the illegal harms Codes. Ofcom will not take further action at this time but will continue to monitor compliance across the sector.

10 October 2025 - Regulations on child sexual exploitation and abuse content reporting repealed

The government has repealed two sets of regulations made under the Online Safety Act 2023 that would have imposed mandatory reporting obligations on user-to-user service providers in relation to child sexual exploitation and abuse (CSEA) content. These Regulations, originally due to come into force on 3 November 2025, required providers to report detected CSEA content to the National Crime Agency, set out technical requirements for such reporting, and activated related enforcement powers for Ofcom.

The revocation, effected through SI 2025/1064 and SI 2025/1066, means that the relevant provisions of the Act - including the reporting obligation and associated criminal and regulatory enforcement mechanisms - are not currently in force. No replacement measures have been announced so far, and the government has not provided reasons for the repeal.

18 September 2025 – Ofcom issues provisional notice of contravention to launches investigation into whether Itai Tech Ltd has failed to comply with the Online Safety Act 2023

Ofcom has provisionally found that Itai Tech Ltd may have breached Section 81 of the Online Safety Act by failing to use effective age verification or estimation to prevent children from accessing pornographic content. A provisional notice of contravention was issued on 17 September 2025, also citing failure to respond to a statutory information request under Section 102(8). Itai Tech now has 20 working days to respond before Ofcom makes a final decision.

16 September 2025 - Ofcom consults on guidance for preserving information about a child’s online activity following their death

Under the OSA, Ofcom can support coroners’ or procurators fiscal investigations into child deaths by issuing Coroner Information Notices to request data from online services. The Data (Use and Access) Act (DUAA), effective from 30 September 2025, requires Ofcom to issue Data Preservation Notices (DPNs) to tech firms to preserve a child’s data and activity following their death, preventing deletion or alteration before a Coroner Information Notice is issued.

Ofcom has launched a consultation on proposed updates to the Online Safety Information Powers Guidance, focusing on the use of DPNs. The consultation also covers minor revisions to the Coroner Information Notices guidance, informed by early experience handling coroners’ requests. Responses are open until 28 October 2025.

11 September 2025 - Ofcom investigates 22 more porn sites under new age-check rules

Ofcom has launched formal investigations into four companies running 22 pornography websites to assess compliance with the Online Safety Act’s new age-check requirements. These sites were prioritized due to their high user numbers, increased traffic since the 25 July deadline, and the risk of harm they pose. Together, they attract over 8 million unique UK visitors each month.
