Services like Reverse Phone Detective are amazingly popular, and they have thousands of users with MILLIONS of phone numbers. There is a reasonable chance that someone will use a service like this to lookup YOUR number at some point or another, especially if you are a mysterious or seedy type of person. If you are uncomfortable about this then you can go directly to the company selling the database and ask for your number to be removed. Most of the time, you can actually do this.

A service that lets you remove numbers is Reverse Phone Detective. Make sure to read a reverse phone detective review before you actually get the service, though.
