Google keeps struggling against link buying, since that goes against the principle of "favouring quality content only".

To that purpose they even set up a denunciation system. Cheer up it's exposure time !

But things are not as clear as they seem, and Google acted quite untrustworthily in the past : with Google Video,   with Google Enterprise solutions page... Shall we denounce Google to itself ?
