According to a BBC News report:
Most households in the U.K. will have pornography blocked by their internet provider unless they choose to receive it, David Cameron has announced. …
Mr Cameron warned in a speech that access to online pornography was “corroding childhood.”
The new measures will apply to both existing and new customers.
Mr Cameron also called for some “horrific” internet search terms to be “blacklisted,” meaning they would automatically bring up no results on websites such as Google or Bing.
You could spend a week reading the comments, which are quite heterogeneous.
