Despite the current panic, there's trouble finding any evidence that any child has actually died in this manner. And of course, there are no deformed ghouls tricking kids into self-harm. Internet curses were barely able to get people to forward emails to ten of their friends, let alone cause suicides around the world. But while Momo may not be real, horrible people using YouTube to prey on children definitely are.
For years now, creeps of all calibers have been infiltrating kids videos. And their biggest tool is YouTube's recommendation algorithm, which through some dark SEO magic easily lets them sneak into YouTube's allegedly safe Kids section. This has allowed weirdos to get toxic videos into playlists aimed at preteens, and has even allowed trolls to edit torture imagery and suicide instructions into cartoon clips in order to emotionally scar small children.
Not only that, but YouTube recommendations have also created a community for pedophiles, as its algorithms gladly help them find like-minded pervs in the comment sections of videos of kids going to the beach or doing gymnastics.
