Many domain name service providers allow you to have a privacy protected domain registration for a small extra fee. This allows you to hide yourself from anyone who does a simple WHOIS lookup to see who owns your domain. The reasons domain owners do this range from wanting to be deceptive to not wanting to deal with the huge quantity of spam and silly link swap requests that get sent to the domain owners contact email address.
Our article review and quality control team routinely performs domain WHOIS lookups to determine if the author of an article owns the domain name(s) in their resource box. If there’s a perfect match, it becomes easier to trust the author or at least give them a bump in credibility. If a URL in your Resource Box returns a privacy-protected whois lookup, it becomes harder for our editors to trust you/and your content.
Bottom line: If you’re in business, think twice before buying privacy guard or hiding your domain WHOIS data from the public. Your market credibility may depend on it.
