Its really creepy and intrusive. But at the same time, I can find really fucked up porn with literally zero effort.
I mean, if your kid has terrabytes of rough incest bdsm porn people will ask why you werent monitoring their internet use, but monitoring them like this feels like a different kind of weird.
Ive told my daughter "Always be nice to the quiet ones and the weird ones. Be nice and be friendly, the extroverts of the world will be fine on their own."
