United Kingdom: Office of Communications closed its investigation into Wojtek concerning its service Gofile under Online Safety Act

On 13 October 2025, the Office of Communications (Ofcom) closed its investigation into Wojtek concerning its service Gofile, following compliance remediation under the Online Safety Act 2023. Ofcom had previously opened an enforcement programme on 17 March 2025 to assess measures adopted by file-sharing and file-storage services presenting risks of harm to UK users from image-based child sexual abuse material (CSAM). The investigation evaluated whether Wojtek had undertaken a suitable and sufficient illegal-content risk assessment and implemented appropriate safety measures, including perceptual hash-matching technology as recommended in Ofcom’s Illegal Content Code of Practice, to prevent users from encountering and disseminating image-based CSAM. Wojtek subsequently revised its risk assessment to better align with Ofcom’s Risk Profiles and implemented a perceptual hash-matching solution using a dataset sourced from persons with expertise in CSAM identification. Considering Wojtek’s engagement and the measures adopted, Ofcom concluded the remediation period and took no further action, while continuing to monitor Gofile’s implementation of the adopted safeguards under Sections 9(2), 10(2), and 10(3) of the Online Safety Act 2023.
