It’s an aggregator that conveniently presents a scary amount of data in one place to anyone who searches for you.
To remove yourself from this web site, search for your name and click on it when it comes up. Then click “privacy”, the teeny, teeny, tiny link at the bottom of the page. Enter the URL and other info and follow instructions.
This info is of course all public, but it’s frightening that it is so easy to acquire in one place. The other scary thing is that you can apparently remove other people’s info as well since there’s no way to verify that you, the remover, are the person you are removing. Very unprofessional and creepy web site. I hope it goes away. To add insult to injury, they got my age wrong.
