Just because “all people” do something, like look at porn, doesn’t mean it’s acceptable to me.

I don’t base my parenting decisions on what the rest of the world thinks. My daughter is the greatest thing that has ever happened to me, and I want to be sure that she is around in 10, 20, 30 years. I feel that the potential for harm to come her way is greater when I let her surf the Internet without my monitoring/blocking sites. Furthermore, she finds sites everyday that I’ve never even heard of! So, it’s not possible for me to be up-to-date on everything that girls her age at looking at. There just isn’t enough time in the day.

Lastly, it’s not for me to judge anyone on here about their parenting skills or lack of parenting skills. Some people go about things differently than me, and that is their right, I suppose. Why do people feel they have the right to judge what everyone else does?

Most of the ISPs in many countries provide unrestricted internet access which allows kids,teenagers browse all unwanted stuff(mostly porn, torrents, and many)

Seriously though, I know what you mean and I personally don’t put a high level of controls on what my kids watch or do – but I do keep an occasional eye on it. They are very cool kids and are very open with it. They are cool about it because we give them a lot of freedom – until they screw up that is.

However, there are parents where a higher level of control and monitoring is really important – so for those parents, they need to know that tools like this are out there and available.

Trying to keep children safe online by blinkering them is like jumping down the rabbit hole. The dark zones of the internet pretty much outweigh the light zones, and pretty soon it would become a full time job. I’d prefer to just straight out say, “Hey look, this is here and that is there. Bad things happen in this area and very bad people hang out in that area. Be aware and keep your guard up. Come get me if you find anything funny.”

One Child Sex Internet Investigations Unit investigator told CNN in 2009, that using monitoring software – either internet or cell phones – simply keeps kids safe. He said, “It makes life easy for me as an investigator. It saves me hours of time, which obviously means I have more time to go out and catch offenders.”

Bottom line is that so long as there is that danger out there, I agree with parents that choose to use this software. It’s not no much a way to block kids from accessing the Internet (although it does have that capability if you have younger kids), but in my opinion the appropriate use of this kind of software is to block the “Internet” from attacking the kids.

Doing that requires keeping them off of sites where they are most likely to come across dangerous elements of the Internet, and the first step to doing that is monitoring all web activity. Unfortunately, there’s no easier way to stay vigilant as a parent against those dangers.
