People should be super careful on the internet.
There are sites out there like the ones you all have been talking about that are basically clearing houses for people's personal (but legally public) data. You can ask for your information to be removed but I believe that has to be done on a yearly basis otherwise people can get your home address, your phone number, and any other number of things that they could use to be creepy with you.
There are people out there who have ZERO qualms about digging up your personal information and using it to try to intimidate you or fuck with you. I have encountered 2 such people in my time since owning this site and have had to have conversations with family members and my staff at work about possible communications from people who get off on fucking with others. Luckily, I have a super supportive boss and family and am not concerned about anyone being able to "soil" my name. (eyeroll intended)
The best thing to do is Google yourself, search different sites, etc. and start sending "remove me" requests to all of hte databases out there.
Also, try to never ever use your real name or indetifying email addresses on public forums. This is sometimes unavoidable as evidenced with Facebook but you can certainly turn off all of the search functions and lock down your information as much as possible
