Why would an individual care if his or her browsing history is published online? Employers search for Facebook or MySpace pages because these websites contain 'proof' that you behaved in some way or other (e.g. pictures), but a browsing history does not tell them anything other than, 'a computer in my household has accessed these websites at some point in time or other,' which can easily be accounted for by explaining that a friend pranked your machine with tentacle porn or your children were just really excited about Misty and Ash Ketchum.
But perhaps the real emphasis is on the following, from TFA:
A fictitious organization calling itself the ICPP copyright foundation issues threatening pop-ups and letters after a virus searches the computer hard drive for illegal content - regardless of whether it actually finds anything.
It offers a "pretrial settlement" fine of $400 (£258) payable by credit card, and warns of costly court cases and even jail sentences if the victim ignores the notice.
If an individual knows that they have illegal content on their HDD they might opt for this $400.00 settlement, as past copyright infringement suits have cost individuals hefty sums.
