http://www.bbc.co.uk/news/technology-18813237 Someone has the knives out for FB. 'those in the know' have known about the level of 'false likes' pretty much since social signals became significant. Its probably right to expect that the big G knows about the vast amount of fakes too. Since FB was floated vested interests have been trying to devalue the stock... The publication of this news is just another cog in that machine. G I reckon will be looking for fake profiles and the amount of other interaction these profiles contribute other than 'likes'.
