Britain to fight porn with 'family friendly' filters

UK internet suppliers will have to block access to pornography unless customers opt to receive it, under a plan by British Prime Minister David Cameron to help parents stop children viewing unsuitable material.

All new customers will automatically have family-friendly filters installed, and existing customers will be contacted and told they must say whether they want to turn those filters on or off. Those who don't reply will have the filters activated.

Cameron urged search-engine providers such as Google, Microsoft and Yahoo! to "step up to the plate" and stop providing results when people search for images of child abuse.

"There needs to be a list of terms - a blacklist - which offer up no direct search returns," Cameron said in London yesterday. "There are some searches which are so abhorrent and where they can be no doubt whatsoever about the sick and malevolent intent of the searcher. I have a very clear message for Google, Bing, Yahoo and the rest. You have a duty to act on this - and it is a moral duty."

He said he wants search engines to report to him by October on their progress.

"There's lots of complicated and difficult questions that have to be answered and that's why we have to work with companies," Cameron said on BBC Radio 2. "I know it's hard but that's not a reason for doing nothing."
