The success rate against YouTube removing terrorist videos is not that great. I guess it all depends on who recieve the complaint and whether he or she are real patriotic or some flaming liberal who want America to lose the war. However we need to keep trying to push YouTube to eliminate the terrorist video posted on their website.
I e-mailed them few days ago asking them to shut Al Qaeda channel on Youtube http://www.youtube.com/islamicstate , islamic state is Al Qaeda in Iraq, but nothing happened. If you can please e-mail radb@youtube.com and ask them to shut down http://www.youtube.com/islamicstate it may help the case.
