A couple of years ago, Alisa Jno-Charles saw her now 9-year-old daughter watching a YouTube video of several children and their swift ninja moves. The video was from Ninja Kidz TV, a YouTube channel that features four young siblings who were raised in a martial arts studio, according to their official website. The channel has about 23.9 million subscribers. Jno-Charles scrolled through the Ninja Kidz TV videos and noticed that the content featured more than just the children’s ninja antics: Every single part of their lives was documented, she said.
