Well dadu I might call you strict but I think Hitler is a teensy bit harsh afterall I am sure your house is not a concentration camp
I dont see the need for it in most cases. If kids are under around 12 then it is likely they are only allowed on with parents supervision anyway.
If they are older i agree it is a little creepy, like sitting next to them all day or following them home from school. In our house there is a firewall to block out anything too filthy as my nice once accidentally googled some rather disgusting porn & came to me horrifiedr & parental controls to limit time (so that hopefully she is not up surfing in the middle of the night) I am aware kids can get around these things if they try hard enough but so far mine has not let me down so there has not been the need to invade her privacy. In the event of some sort of inappropriate beavior my instinct would be to punish by limiting time or priviledges over following her every move.
One thing that parents need to be aware of is that this is a form of spyware and can make you more susceptible to viruses etc.
Xero I think this is just one of those hot topics because it was not around hen most of us were little kids so there is no yardstick to measure with.
