This week nearly 20,000 Facebook users were duped into 'liking' a rogue fanpage called 'The argument that disproves atheism'.
Like many other users, I clicked on the link that appeared in my newsfeed, mainly due to curiosity at what had come over my friend to post such a link.
A sizeable group of us were caught out, suddenly and inexplicably 'liking' a fanpage without the usual button-clicking. Just clicking a normal looking link seemed to be enough, which has scary implications for Facebook's 'social graph', if it can be gamed so easily.
Fortunately, while people might have difficulty removing the notification of the 'like', it's simple enough to remove the application from your profile altogether.
