Meta is suing a company that ran ads on its services to promote an app that lets people create nonconsensual, sexualized images of others using AI technology, the social media company said Thursday.

The lawsuit is against Joy Timeline HK Ltd., which develops the app called CrushAI and its variants. The Hong Kong-based company ran ads on Facebook and Instagram to promote CrushAI, an app that uses artificial intelligence to take a photo of someone and create nude imagery of them.
