By the time I was 17, at least on my windows PC, every search I made was reported. Every setting I touched was reported. Every app I use, and how long, reported. Every startup and shutdown reported. Games with chat features were banned. Online games were banned. Every week on Sunday, an email with all this went to my parents, and my dad would forward it to me as a kind of intimidation that "we know all"...

And yes, they used geofenced tracking too.

But I'm a geek, so my Linux laptop and phone were no longer bugged (my only access to other people at the time) by the time I figured it out (around age 16).

Still had to turn the tracker on so they wouldn't ask why the location pings stopped though.

This kind of obsessive control ought to be illegal. I propose privacy rights at age 16, enforceable by fines, with a safe hotline for those with obsessive parents. They were emotionally abusive, control by external restrictions is often only part of the story in cases like mine.

I'm all for safety filters, but parental controls that can be classified as spyware have no place in a parent-child relationship after the age of 16...
