Your child's bedroom door is closed. Inside, a stranger who has never met them is counting down the seconds until they cut deeper, swallow the pills, or hang themselves on a livestream for dozens of cheering spectators. They call it "764." The FBI calls it modern-day terrorism. The survivors call it the night they never came back out of their room the same. In the last four years this entirely online cult, and its copycats, has driven children to suicide, necrophilia, child-on-child rape, and school-shooting threats, all orchestrated from Discord servers, Roblox games, and AI chatbots that write perfect grooming scripts faster than any human ever could. Australia just banned every major social platform for the under-16s and watched 764 recruitment collapse overnight. The rest of the world is still pretending it can't happen here. This is not a "screen-time" problem. This is a slaughterhouse built on algorithms, funded by your child's attention, and run by other children who were broken first. Close this book and nothing changes. Open it, and you finally see the countdown that has already started in a bedroom down the hall. You still have time. But not much.
