Sites like Bebo, Friendster, Facebook and Myspace have fuelled the social networking trend.

In addition, there is a perceived privacy threat in relation to placing too much personal information in the hands of large corporations or governmental bodies, allowing a profile to be produced on an individual's behavior on which decisions, detrimental to an individual, may be taken.
