Encourage anonymous browsing of web sites
Surfing anonymously over the Internet is the safest way to protect your privacy and ensure no release of personal information or data. A person should be able to browse the Internet in the same way that someone can window shop in a shopping arcade without revealing his/her identity, even if he or she makes a purchase.
Therefore, a website should encourage anonymous browsing, or at least give visitors an informed choice about whether or not they need to disclose their identity.
