The latest of these is a worm forces users to like the page, thus spreading it inadvertently through postings on Facebook walls. The result is thousands of wall posts for a page entitled “Shocking! This girl killed herself after her dad posted this photo.” Clicking the link enclosed spreads the worm further. Unfortunately, this is not the first time we’ve heard of such an exploit, but according to Facebook Search, a lot of people have been affected by this one.
As worms go it’s fairly harmless if annoying. It does not compromise Facebook profile security nor does it scout out for passwords and login names. But annoyance is an important factor. We hang around Facebook because it is convenient and in the little time we spend online it makes sense to catch up with friends and see what’s new. If the experience begins to get tarnished then Facebook may find that its popularity begins to wane.
