I'm happy to be corrected. But my understanding is that this is a government programme introduced in their manifesto and applied by "voluntary" means by the big 4 ISPs, with a strong government understanding that the others will soon fall into line. That's what I mean by "central". As for the "control" part, maybe I have misunderstood. Do you mean to say the ISPs have not included things like the IWF into their censorship mechanisms? Because that looks to me like a list of things to compulsorily ban. Now, I may be putting two and two together, but to me this looks like: a) The government at a minimum "influencing" ISPs to introduce variable-level filtering. b) Mandatory filter lists. c) An onward programme of debate about what should be in or out of the block. As for the Ryan Giggs thing, that was simply my speculation. However, I'm currently finding a lot about the way that politicians see control measures goes beyond my wildest fancies - eg RIPA used for school catchment areas.
