Parents are desperate for help to protect their children from harmful social media platforms following two bombshell court rulings last week that fined the tech giant Meta with penalties in the millions .   “Ninety-five percent of our kids are using these products that we know are harmful,” Julie Frumin, a 43-year-old mother of two from Westlake Village, north of Los Angeles, fumed to The Post. “We need help. Help us!”  But others finally see more than a glimmer of hope in the wake of the cases.
