You've confused this with Twatter, if you think you can silence responses you don't like here.
If you're so addicted to social media yourself that you can't imagine your children or yourself without it, don't blame the messenger.
If those digital tools were possible, you would have already found them in your own social media experience.
IRL, the same tools that kids used to be kids and socialise for generations or centuries still exist - clubs of all kinds, theater and concert outings, dance socials, religious/community social and educational events, volunteering, just chatting on a landline , and so on...
Those do take more parental involvement than just giving the kids a digital "tool" and hoping it's free of everything harmful.
