Youtube has been quietly banning videos and accounts of people who post anti islomofacist or anti Muslim videos. Some racy some tame some simply videos that contain a Danish cartoon or two.
See http://crusader18.blogspot.com/2006/09/crusader18-user-account-suspended-by.html and http://michellemalkin.com/archives/006048.htm . The second link shows a banned video that is very tame.
On the flip side I've seen no banning of all the islomofacist propaganda videos by groups like Hezbullah that are much more hardcore in hate and some show brutal torture and death. (search for Hezbullah, Zionist,...)
