Piper Leypoldt, 11, is from North Carolina. She watches cooking videos on YouTube. Piper knows that the site collects user data, such as her search history. She's not worried. "Other websites I use at home and school also collect my information," she says. But advocates for online privacy are worried. The Federal Trade Commission (FTC) said the site collected kids' data and used it to target them with ads. The FTC says YouTube did this without parents' consent. That made it illegal. YouTube started in 2005. The site is built to keep you watching. Artificial intelligence learns what videos you like and recommends similar content. YouTube has agreed to limit the data it collects on videos for kids. It will also require creative content to identify videos made for children. Advocacy groups say it's not enough. They say YouTube should decide if a video is for kids. Otherwise, "it's like having a school playground with no one responsible for watching the kids and making sure the equipment is safe," wrote Susan Grant.
