The root of the problem as I have mentioned previously is that the propaganda is actually effective. And until you identify the reasons why this is the case, and directly start addressing those reasons, whatever actions you take aren't going to make much of a difference. Banning propaganda from "vocal jihadis" won't make their words any less appealing. And no matter how good your technical controls, it won't prevent a motivated person from finding such material online, one way or another. And while there are many reasons why the jihadi message is so effective, I happen to believe that it is sustained not because the ideas are being widely and indiscriminately dissiminated, but rather because the ideas are not being exposed and challenged. It is bizarre that there are people committing mass murder, motivated by a concrete and well-documented set of beliefs, which nobody is criticizing let alone even willing to discuss in public. Doesn't that sound to you like "they are afraid of us"? I'm sure that's how it looks like to a jihadi recruit.
