Don't think for a minute that because your kids "don't watch that kind of stuff online" that they don't know about Momo. Some idiot jacked the image of sculpture in Japan from a special effects company to use as "Momo". She contacts kids through various videos they are already watching, like Peppa Pig, and tells them to chat with her on WhatsApp and if they don't do as she says, she will curse them. Watch the video to get more info.
