Anybody who's willing to pay online information brokers - also known as people-search sites - can learn your phone number, address, criminal record and a lot more.
Primary data brokers like Intelius collect information from public records. Secondary data brokers like Spokeo aggregate information from primary brokers and add data collected from social networks and other online sources.
If you truly want to disappear from the Internet, you should search for yourself on these sites and remove yourself from their databases.
The privacy company Abine had a paid service called DeleteMe that removes your information from 25 major data vendors and makes sure you aren't added back. If you don't feel like paying, Abine also provides instructions for opting out of each service.
Each site's opt-out procedure is different;some even require letters and faxes! It will take some time, but it's worth it to preserve your privacy. You'llwant to regularly check to make sure your information hasn't been put back.
