This question is sort of a carry-over from last week's question, "What can the Internet Do for Me?". There is a price to be paid for all of the readily available information we see and share over the web.
In this day and age, everyone leaves what's called a "Digital Signature". You don't even need to own a computer!!! Every time you apply for a credit card, or use a credit card, or get a driver's license, or buy a house, a record is made. Today of course, nearly all records are maintained digitally.
The previous posts were correct about the site you mentioned being an aggregator, but they aren't the only ones. Not by a long shot. With about $35.00 and a little leg work, your entire life's history is out there for everyone to see. I'm not saying that I like it or dislike it, but that's the way things are.
There are some people out there who try to evade this kind of tracking using a method commonly called "Going Off the Grid". In order to accomplish this, an entirely new lifestyle has to be adopted. They pay for everything in cash. They don't work, or if they do work it's off the books so their social security number doesn't show up. They don't pay taxes, and they don't have a home address. They can't rent a car or fly on any legitimate airline. Some go so far as to completely avoid public places for fear of being identified by video cameras attached to facial recognition software. In other words Bryan, it's really difficult to keep what used to be private.....private.
I wouldn't worry too much about the information on the site you listed. They don't really know all of your secrets, just the ones that you publish or allow to be published on your behalf. Some information is and always has been available by law such as property records, criminal records and other public records. When I entered my name at the site, they came up with hundreds of people with the same name. When I narrowed it down to give them my street name, they still didn't get most of the information right.
Most important for you Bryan, is to make sure that you have a good firewall in place on your computer. Use strong passwords and change them often. Avoid giving out your personal information over the internet, and relax. After all, Big Brother is Watching!!!
My Grandmother once told me when I was a boy so many years ago, that I should never put anything in writing that I wouldn't want published on the front page of tomorrow's newspaper. She was sure a smart ole gal.
