Ofcom has launched an investigation into the social media platform X, owned by Elon Musk, following reports of sexually explicit deepfake images created using the Grok artificial intelligence tool. The BBC uncovered numerous cases where women's images were manipulated and shared online without their consent, prompting concerns about the platform's ability to remove illegal content swiftly and prevent further harm. UK authorities have warned that failure to comply with regulations could result in X being blocked in the country, as the issue has sparked international criticism and led to temporary bans of Grok's image generation feature in Malaysia and Indonesia. The investigation is considered a top priority, with officials emphasizing the need for online platforms to protect users from illegal and harmful material.
