Domain Privacy Service
Private by Design replaces your WHOIS contact information (Name, Phone Number, Business Name, and Address) with its own information. It then forwards any emails to you. That way, you still receive all legitimate notices relating to your domain without having to make your personal information public and suffer through all the resulting spam.
You can add privacy to any domain in your account that supports it for free. Just log in to your account and click the icon underneath the "WHOIS" column to the right of your domain! Simple, fast, anonymous.
