7. Can we trust the privacy policies of Web sites? Most of the web site providers give assurances that they will never share or give any information about their customers. But most of the time these companies can’t keep up with their promises. One example is InfoBeat, a news letter published by Sony Music. In InfoBeat privacy policy, they promised to never to give out a subscriber’s Email address: http://www.infobeat.com/static/cgi/static_merc.cgi?page=integrity.html& ( We will NEVER release, sell or give a subscriber's name or e-mail address to any other party or organization, without the subscriber's explicit permission).
