Of course there are. One can't handle Internet. It handles you.
When I was in the age of preteen/teen I got everything I wanted. Everything. Sure, today isn't very different from the past. If some teenager pricks want to use meta, watch Netflix or do some nasty chat & greet chat roulette - they're just do it. We need to teach them how to handle that dickheads they may see and the do's and don'ts. this should be without tabooing.
