Meta said that it had filed lawsuits against several people in Brazil who promoted fake or unapproved healthcare products and online courses promoting them. The company also sued a China-based entity it says used ads featuring celebrities "as part of a larger fraud scheme that lured people into joining so-called investment groups." The company didn't provide details on how many ads these groups had run on Facebook, how many social media users had seen or interacted with the ads or how long the scammers had been operating on the platform.
