I was that teen! Online social platforms saved my life when abusive and helicopter-y parenting was gunning for the opposite. That was a different time, though, the internet has gotten significantly worse.
Seriously, people need to just be decent goddamn parents. I don't understand why you'd have a child these days if you don't know how to navigate parental controls on-device and on the network level. You'd be neglecting your child otherwise, shit's different nowadays.
