Honestly, I don’t have a perfect answer. It really depends on what the service is.

My main thing is I want to be able to opt in or out of various filters. I don’t mind if my kids want to listen to music that has swear words, but I don’t want them watching videos where they give horribly sexist pickup artist advice.

This isn’t just about what I feel is age appropriate, either. It is also about what I know about my kids.

My 10 year old hates scary things, and she gets completely freaked out when they show scary movie previews. I would like to be able to block those for her. On the other hand, my 7 year old is obsessed with scary things and I don’t mind if he plays zombie video games.

The internet is too dynamic to build a working filter around. Perhaps just tools which help parents quickly and efficiently monitor their child's device usage would be best.

Do you want to alter behaviors or lock children in a gilded cage?
