The problem is, Google has caught three music publishers doing just that, and deleted billions of video views in response.
RCA, Sony/BMG, and Universal, have all been found to be using online services in order to generate more views for specific videos. By doing this it creates more interest as the videos are seen as being popular and in turn get more exposure. But views also generate revenue for both Google and the music publishers from the adverts positioned next to them.
The extent of the artificial views is quite staggering. RCA had managed to add 39 million fake views to its videos, Sony/BMG added 847.7 million, but Universal is the worst offender and has had well over a billion fake views removed from videos. I can only imagine the impact those views had on the exposure and revenue-generating ability of each video.
