Putting the power to censor the internet, no matter how stringent or specific the guidelines, into the hands of a private organization is misguided. It is the state not individual ISPs who are needed to assess how dangerous a site is, whether it is actually promoting extremism, and ultimately make a decision as to whether a site needs to be blocked. The ISPs may end up being the actors that implement the policy but it has to be government that decides which websites to block and why. This also means that the decision would be much more centralised. Leaving this decision to the discretion of individual ISPs will mean that some websites will be blocked on some ISPs and not on others. Only government can ensure that there is consistency.
