I'm tech savvy, raised my kids internet liberal, gave them lots of freedom and educated them so they could protect themselves without adult supervision. Training to cope with unexpected situations is far more important than withholding them from exposure because you won't be there when it eventually does happen. They are now very literate and use those skills to get the best out of university.
With all their experience and knowledge, they are now warning me: "Dad, facebook/instagram has become a toxic cesspool that isn't fun anymore and should be avoided at all cost!!"
If that isn't a signal to protect youngsters...
