Grok - the AI chatbot developed my Elon Musk's company - is facing growing international backlash for being misused to generate sexually explicit and nonconsensual images. Malaysia and Indonesia have become the first countries to block Grok over the weekend, while a UK media regulator launched a formal investigation into the platform X on January 11. The scandal is fuelling debate on generative AI tools that can produce realistic images, and the lack of safeguards failing to prevent its abuse.
