It's just more politics - rather like the UK Newzbin copyright case pursuant to which BT was ordered to adopt a filter "Cleanfeed" that they have been using for at least three years(!) which blocks access to proscribed sites and gives a "404 not found" error in stead and (IMHO) logs the user. Fine and dandy when used to block kiddieporn, more contentious when it blocks copyright infringment (compare YouTube and Google Video running like rabbits for "mere conduit" protection under the DCMA and pirates abusing DCMA counternotices) but freaking alarming if (what am I saying? "if"? - hollow laugh) when it comes to political censorship.
