Dupple writes with news that the British government is considering restrictions for ISPs that would block by default anything considered "adult content." From the article: "Ministers are suggesting that people should automatically be barred from accessing unsuitable adult material unless they actually choose to view it. It is one of several suggestions being put out for a consultation on how to shield children from pornography. Websites promoting suicide, anorexia and self-harm are also being targeted. The discussion paper asks for views on three broad options for the best approach to keeping children safe online, in a rapidly changing digital industry. ... The latest system, called 'active choice-plus,' is aimed at reaching a compromise. It would automatically block adult content, but would set users a question, along the lines of whether they want to change this to gain access to sites promoting pornography, violence and other adult-only themes. This is partly based on 'Nudge' theory, a U.S. concept which states that persuasion, rather than enforcement, can be an effective way of changing behavior."
