A domain name might need privacy depending upon the circumstances. If you need to keep your personal information private then definitely you will require privacy. The privacy option is offered for an annual fee.
Owning a domain name instantly lists your individual and contact information in the WHOIS of the domain you hold. This openly available detail may reveal you to: mass unwanted commercial e-mails (SPAM), other trash e-mails, telesales calls, any other known or unknown misuse with your identification details. Domain Privacy Protection protects your private details from public view, protecting you from unwanted marketing, frauds, spying eyes and worse. http://www.registerprivatedomain.com/articles/Domain-Privacy.html
