Here's the truth: when you REGISTER your domain name, all of your pertinent personal information (name, home address, telephone number, email address) is published in the Whois Public Internet Directory. The Directory can be viewed 24/7 by anyone, anywhere on the planet! (This is legally required by the Internet Corporation for Assigned Names and Numbers as part of the domain name registration process.***) Once your information is online, it can be harvested by criminals, newspapers, bloggers, "blogging gurus," telemarketers, spammers and hackers and a laundry-list of unsavory characters and organizations to gain access to your financial and personal data.
THERE IS A WAY you can protect yourself, your loved ones (and maybe even your job) - it's called private domain registration, and in this case, it is really and truly PRIVATE! You can choose to re-register an old domain name or start a brand new one.
Here's something else to consider: A lot of folks who begin a new business are currently employed. They may not want their employer to know that they are trying to branch out on their own - it may even be prohibited by the company they work for! A private registration keeps your activities seperated from your other online endeavours.
