The British media regulator Ofcom has launched a formal and high-stakes investigation into the social media platform X, concerning its integrated AI chatbot, Grok, and its role in the generation and sharing of non-consensual sexualized deepfakes, including images of children. The probe by the UK’s independent online safety regulator follows deeply concerning reports that the Grok AI tool was being deliberately exploited by users to create "undressed images of people" and "sexualised images of children," a category of content that is illegal in the UK and may amount to intimate image abuse, pornography, or child sexual abuse material[1][2][3][4]. The swift action underscores the growing global alarm over the ethical failures and inadequate safeguards within rapidly deployed generative AI technologies.

The investigation is a direct test of the UK’s new regulatory framework, the Online Safety Act, which places a legal duty on social media platforms to protect their users from illegal content[1][5][6][7]. Ofcom is specifically assessing whether X has failed to comply with key obligations under the Act, including whether it properly assessed the risk of UK users encountering this kind of illegal content and whether it carried out updated risk assessments before introducing significant changes to its service, such as the Grok AI image generation feature[2][8][9]. The regulator had initially contacted X on January 5, setting an urgent deadline of January 9 for the company to explain its user protection measures, and after an expedited assessment of X's response, decided to escalate the matter to a full formal investigation[1][2][6][4].

The controversy centers on Grok's image generation and editing capabilities, particularly a feature that users could exploit to digitally "nudify" or alter real photographs of individuals, including well-known celebrities and private citizens, into sexually suggestive or explicit images without their consent[10][11][12][13]. Reports indicate that users were able to tag the Grok account on X and use simple prompts like "put her in a bikini" to generate images with the person's clothes removed, a process that proved to have lax moderation filters[4][12]. The issue became acute when reports emerged of this capability being used to create child sexual abuse material[1][5][14]. Deepfake detection companies estimated that, at one point, Grok was generating a non-consensual sexual image roughly every minute[13]. Following the widespread outcry and initial contact from regulators, X moved to restrict the public image generation and editing feature to only paid X Premium subscribers, a step that critics, including Downing Street, labeled as turning a feature that allows the creation of unlawful images into a premium service[15][16][10]. The company's owner publicly stated that anyone using Grok to make illegal content would "suffer the same consequences as if they upload illegal content" and that the platform would remove illegal imagery and work with law enforcement[15][10].

The international backlash has been substantial, highlighting a critical new challenge for content moderation in the age of generative AI. Governments and regulators beyond the UK have also taken action or expressed grave concern[17]. For instance, the Australian eSafety Commissioner is investigating Grok's role in generating sexual abuse deepfakes, while both Malaysia and Indonesia have temporarily blocked access to the Grok chatbot over the risk of AI-generated pornographic content[17][14]. In Europe, the Commission ordered X to retain all internal documents and data related to Grok until the end of 2026 under the Digital Services Act, and French authorities are also investigating[17][12]. The global coordinated response emphasizes that the Grok situation is not an isolated incident but a major safety failure that exposes the weaknesses in AI safeguards and the ethical boundaries of platform-integrated generative tools[11][12][13].

For the AI industry, this investigation carries profound implications, setting a potential precedent for how quickly and aggressively regulators will move to govern technology's output rather than just user-posted content. For years, the creation of deepfake videos, which are overwhelmingly pornographic and depict women, has been a major problem, with an analysis finding 98 percent of deepfake videos on the internet are pornographic[13]. The integration of powerful, easily accessible image manipulation tools like Grok into a mass-market social media platform represents an "industrialisation of sexual harassment," a phrase used by a German media minister to urge strict European action[12]. This shift mandates that AI developers and platform owners build safety and ethical guardrails that can withstand malicious or abusive prompting from the outset, rather than relying on reactive measures.

Should X be found in violation of the Online Safety Act, the penalties Ofcom can impose are severe, including substantial fines of up to ten percent of the company’s global annual revenue or eighteen million pounds, whichever is greater[3]. Furthermore, the ultimate sanction is a court order requiring internet providers to block the site or app entirely in the UK, a possibility that has been publicly supported by members of the government if the regulator's findings warrant it[6][16][10]. The Technology Secretary has previously slammed the rapid spread of these deepfakes as "appalling and unacceptable"[12]. This looming threat highlights the new era of accountability for Big Tech under the Online Safety Act, signaling that the UK is prepared to use its full regulatory force to enforce digital safety, especially concerning the protection of children and vulnerable users from AI-driven abuse[5][16]. The outcome of Ofcom's probe will likely shape the design, deployment, and moderation policies for every generative AI tool integrated into social media platforms worldwide.
