And your closing statement is what I tried to explain to Blam the other day in another post.
One problem is one does not need to use web sites, but only maintain well updated email address lists. But again I am not saying I am against your suggestion to have all known sites and the thousands that re-pop up extinguished as they are made known.
Of course DNS server farms in the far east and associated ISPs will find a lot of new business. The Internet is not what it was fifteen years ago.
And a DNS server(s) can exclude access of the main stream, and only allow those servers at ISPs to have access by choosing.
In fact this is what China has been up to. They are building their own Internet Backbone. Likewise, eventually the Islamic world will move in that direction. It is just a matter of time.

Correct, notice in my original post how many terrorist websites are based in Malaysia, a muslim country in Southeast Asia. However there is a world wide internet protocol that prohibit the use of terrorist materials and even those internet providers in Malyasia must abide by it or they will be shut down.
