Why X faces UK ban over Grok deepfake nudes

Ofcom has launched an investigation into X over reports that the social media platform’s AI chatbot Grok is generating deepfake nudes of people without their consent, as well as sexualised images of children.

Under pressure to act, X last week limited access to Grok’s image generation tool to paid subscribers. This was criticised by Downing Street as merely turning “the creation of unlawful images into a premium service” but, said No. 10, it proved X could move quickly to address the problem if it wanted to.

Now the UK media regulator could follow Malaysia and Indonesia in blocking Grok, or go one step further and recommend suspending access to X altogether.

How serious is the problem?

“The ‘put her in a bikini’ trend began quietly at the end of last year before exploding at the start of 2026,” said The Guardian. “Relatively tame requests by X users to alter photographs to show women in bikinis” quickly turned into “increasingly explicit demands for women to be dressed in transparent bikinis, then in bikinis made of dental floss, placed in sexualised positions, and made to bend over so their genitals were visible”.

Analysis by the newspaper found that, by the end of the first week of January, as many as 6,000 bikini demands were being made to the chatbot every hour. Some requests “asked for white, semen-like liquid to be added to the women’s bodies”.

“None of this should come as a surprise,” said Clare McGlynn in The New Statesman. Elon Musk’s AI chatbot was “designed to have fewer ‘guardrails’ than its competitors”.

While images of naked, non-consenting women had been “circulating with impunity on the platform for weeks”, the final straw, and what appears to have finally prompted Ofcom to act, was when Grok generated images of the Princess of Wales in a bikini.

What action could Ofcom take?

Ofcom will investigate whether X is in breach of the Online Safety Act, specifically whether non-consensual undressed images of people “may amount to intimate image abuse or pornography” and if sexualised images of children “may amount to child sexual abuse material”.

Under the law, the regulator can fine businesses up to £18 million, or 10% of their global revenue, as well as take criminal action. It can order payment providers, advertisers and internet service providers to stop working with a site, “effectively banning them, though this would require agreement from the courts”, said The Independent.

Technology Secretary Liz Kendall has said the regulator would have her “full support” to block access to X in the UK if the platform was found to be in breach of the law and refused to comply.

“Other parties want Ofcom to move faster, or get out of the way,” said Politico. The Liberal Democrats have urged the National Crime Agency “to take charge”, arguing that “the situation went well beyond Ofcom’s remit as communications watchdog”. It comes after the Internet Watch Foundation warned that criminals have used Grok to create child sexual abuse imagery.

“We cannot wait for a far off verdict,” the party’s tech spokesperson Victoria Collins said, calling for Ofcom to immediately block X from operating in the UK while a full investigation takes place.

What has the reaction been?

Billionaire X owner Elon Musk said the UK government “wants any excuse for censorship”. A ban would also “cause uproar in Washington”, said The Telegraph. The White House has “become increasingly hawkish towards attempts to censor American companies and its citizens”.

There is a “chance” that blocking X in the UK could lead to the US sanctioning British officials, starting with those working at Ofcom, said The New Statesman’s US correspondent Freddie Hayward. “These threats are sold to Americans as free speech protections, but they are also designed to force the British government to change course.” Depending on the outcome of the Ofcom investigation, Keir Starmer “might have to accept that protecting free speech has become an issue of national security”.
