Points to a disproportionately large number of posts about the political candidate Ron Paul that were buried on Digg, in support of the premise of that so-called "bury brigades" exist on Digg, groups of users who vote against articles en masse when they don't like them, "philosophically".
This should surprise absolutely nobody who is familiar with Digg's basic operating principles and has been online for more than ten minutes in his life, but sometimes people need evidence in support of the obvious.
Putting the feeedom to be heard on a topic to a vote - how do people expect that to work out?
