I am proud to be a Vigilant who takes the terrorist websites down. As far as intelligence value of these terrorist websites, the author of the article is wrong, there is little intelligence value to be gotten from these terrorists websites/forums but on the other hand they are doing vastly much more damage to our national security and the security of the world by recruiting more terrorists in each passing days, spreading terrorist propaganda and hate, and teach the terrorist how to conduct terrorist acts.
They must be shut down.
