I think that, by intentionally posting unlikeable things, he guarantees himself 100% spam likes. On something that's actually likeable, these spam likes might be contained to a reasonably small proportion of likes.
But what is the size of this shadow population of click farm users on Facebook? For these countries with large click farms to be the largest contingent of likes on big pages like David Beckham suggests they are not small enough to be manageable...
