Online reputation and Offline reputation

Hi, here is an example that has received significant publicity in Canada on how your reputation in your physical life can been influenced by your online activities. Online activities in this article are in Facebook, and the people concerned are recruits to become Border Control Guards. What is interesting is that this may have passed by unnoticed if it wasn't for some data-mining done by a Border Guard (who worked only temporarily) who was passed over for a permanent post by these young cheaper recruits.
