Here's the problem with the logic of blocking all of the most popular
sites; they tried this from time to time in Afghanistan on the
NIPRnet. Whenever someone was unable to get to YouTube, Facebook, etc.
they, still bored and/or wasting time, simply went to some other web
site which also wasted equally as much bandwidth.
