Here is how I look and deal with this. If someone wants to find you. They will. They don't really need the internet. IT IS HANDY... for stalkers and crazies. Yes. People using the internet need to start with something in there minds. ANYTHING YOU DO here is recorded. Somewhere, some how on a server farm, in an email data bank, on a hard drive. Its all there for time memorial. Even when you think you have lost something... its still there. All a computer is, is a compilation of number sequences. You cant just blast em, and they are gone. Some one was saying you can purchase software to hide your trails, no your not hiding them, your just rearrainging them and confusing the normal user. Hackers will still be able to find your trail IF THEY ARE REALLY wanting to come after you.
Before computers, the sickos' went through garbage, and stole mail, they would use that dinosaur called a phone book, and ease drop on group discussions at churches and a get-together.
Tomorrow they may invent something that lets us link our brains telepathically. Someone will find a way to see into that too. Its the law of nature and balance.
Simply put if you don't want people to find you on the internet and look into the deepest part of your soul. DONT PUT IT OUT THERE to be looked at. As far as people reading things you wrote. Whats the difference if you wrote it on a piece of paper and dropped it on the ground? Its free advertising and if you are complaining about something that is not right about it, well that's maybe a good thing, and someone needed to see it.
I am worried daily about how sick the mind of humans have gotten. I figure, I am sort of careful. I have normal checks and balances in place, but really if a freak wants to find me, he will and he doesn't even need a computer to do that.
