Clicktrails

Clicktrails are information derived from an individual's behaviour, pathway, or choices expressed while visiting a web site. They contain the links that a user has followed and are logged on the web server (the ISP's computer, for those who do not run their web server).

Clicktrails are normally used for troubleshooting and system maintenance purposes. However, clicktrails can also be misused to record profiles of the habits, tastes and online activities of an individual user. Information thereby traced (depending on the type of information) can adversely impinge on a person's privacy by targeting an individual for marketing a product or by fraudulently soliciting business from an individual. Please give some examples of how clicktrails can be used.
