British prime minister David Cameron explained his plans about the child pornography blocking campaign which he urged giant tech firms to support yesterday. He said that while access to pornography is still an option to users, child pornography will be universally blocked.

Installing a new broadband service will automatically filter pornographic content, and those who wish to access adult content must manually turn the filter off.

"By the end of this year, when someone sets up a new broadband account the settings to install family friendly filters will be automatically selected. If you just click 'next' or 'enter', then the filters are automatically on," explained the prime minister.

However, copyright owners are at risk of losing profit from forced content blocking, explained analysts. Current filtering services such as Talktalk have the option of blocking out legitimate sites such as file sharing services and registered adult streaming sites. Voluntary filters endanger some areas of internet business, according to opposers of the Child Exploitation and Online Protection campaign.

Others also believe that blatantly blocking the sites could actually drive the traffic even higher for child pornography sites. Pirate Bay, a file sharing site, said that their traffic rose after being blocked by certain policies and technology.
