The status quo is girls (or their marketing teams), randomly "quick add" profiles, exposing minors to their teases and adult content.
You're pretty much guaranteed to see unsolicited prn in sc these days. Just create a fresh account and wait for the random friend requests.
Kids are going to be exposed anyway but better to have exposure at a time where theyhave the maturity to handle it.
Education takes time and is hard. It is very nice as parent to know that my kids have some relatively safe social apps.
