True, but nothing beats out active parenting and communication. Like has been said, you can set up filters all day long (and you should), but the second the kid learns how to install a distro from scratch, they’ll soon have unfettered access the the entire Internet. The only sensible approach is to talk with them about what’s out there, the dangers of it, and how to navigate the internet safely. Also too, browse with them. Spend time with them guiding them on the wonderful parts of the internet, and help them develope good habits on being a good netzien. Eventually they’ll find the seedy parts of the internet, but hopefully by then they’ll be less interested in it because it isn’t taboo, it’s just wrong.
