I'll throw my hat in the ring..........
I am a Nazi parent. My kids (8 and 10) have no rights. They have the right to choose what kind of cereal to eat in the morning.
I check logs, and I use a keylogger which also takes a screenshot every 60 seconds and sends me alerts via email.
I also block as many sites (or keywords) as possible
More than one reason for this. First,they are too young to be viewing pron, and I only have them Wednesdays and every other weekend. If they go home to mom describing what they saw on the internetz at Daddy's house, that would be the absolute wrong answer. It would be ammo to use against me.
How one uses the information gained from the keylogger is the issue. I do not use it to punish or to point out their wrongdoings in a fascist manner. I try to take the approach of "I see you were searching about X on the web. Is there something you are curious about that I can help you understand better?" I also like the screenshots to see who is texting THEM, and WHAT they are being texted.
This may be a bit extreme, but it is how it happens in my house.
Kids need to be protected, but not sheltered. I am the parent, not their friend. Time for friendship is when they are grown. Right now, I am perfectly happy with them fearing me. Fear is the most primal of human emotions, and it does not require a developed sense of logic, or right and wrong.
There are too many parents who claim "My daughter would NEVER do that. She is too smart/mature/well behaved to do anything like THAT! She never dresses like ________, or acts like _________, and I give her space and privacy"
This is usually the daughter pulling a train on the football team.
It is the responsibility of all parents to monitor what their kids are doing. I used to date a girl in school whose father would take the door to her bedroom off the hinge when she had company (a.k.a. boys) until she was 18. He also showed me two of his possessions when I first met him. One was a Colt .45, the other a shovel
Extreme? Probably.. Effective? Very.
YOU are responsible for your kids actions until they are of age. It is YOUR responsibility to make sure they are doing the right thing until they are old enough to know what the "right" thing is, and put it into practice. I personally don't give a damn which technique works for anyone else. If it is effective for you, kudos.
I, for one, know what I was like as a kid.
It used to be that one watched, listened and paid attention to their childrens' activities. Modern times just means modern techniques.
