Hmm only cookies are used to target people? How about a hash of IP location, browser, video screen size, privacy options enabled, flash, javascript... Seems your browser reports plugins to the webserver when you visit any site. This information can be used to track your actions, serve you content and determine certain probablities - all without a cookie being set.
