"PIR distinguishes between those listed in NameBase, and those who use NameBase. This distinction is based on the conviction that individuals and groups who have some measure of political, social, or cultural power, automatically forfeit their privacy rights to the precise extent that their power influences the lives of others. This principle is not only philosophically sound, but it is also a legal principle. For example, U.S. libel law makes a distinction between a 'public' person and a 'private' person."
