Many months ago there was discussion in Campaigns and then Site_Stuff about the Government proposal to encourage / force ISPs to put website filtering / blocking into use (at consumer cost, no doubt) and initially MNHQ was supportive. Technical arguments won them over to seeing this as a poor method (even if the motives appear to be good) and many were happy to see them reject the proposal.
UK Parliament has now started to collect views on the pros and cons of website blocking, with the aim of reporting about it in November (presumably for the Minister to decide whether to expect or legislate on ISPs blocking sites), but seen with the background of Ofcom saying it isn't that practical, it still strikes me as a 'white elephant', and I hope the Minister forgets this silly idea once and for all.
(FWIW, under Labour, their Minister wanted 'film certificates' for every web page and then had it pointed out that something can go from 'U' to 'XXX' if a single image is posted/ uploaded onto that page! So it isn't just this government with daft ideas about how to censor the internet to 'protect the children'.)
I put a summary of the main points *> online here
