Likely the reason was what is described in this video (topped HN some two weeks ago): http://www.youtube.com/watch?v=oVfHeWTKjag http://www.youtube.com/watch?v=oVfHeWTKjag TL;DW: there are tons of India/Bangladesh/Brazil-based spammers (those "buy 1000 likes on FB for $1" etc) who allegedly in order to prevent being caught by fraud detection algorithms, are liking whole array of random pages.
