A few years ago I parodied the last government's determination to ban things with a proposal to ban masturbation. David Cameron is trying to make this a reality- with moves to make people apply with their full name and contact details as they ask their ISP if the can watch pornography. Not child porn, but consensual adult porn.
Forcing people to make details of their private sexual behaviour known to their broadband providers is intrusive to an extent that is hard to overstate.
Cameron says it's about protecting the children, but his obsession with stopping teenage boys having a wank looks positively Victorian and is downright creepy. At least the Victorians turned their anti-masturbation zealotry to invent good stuff like Cornflakes.
