Google and Microsoft crackdown 'won't stop child abusers'

Campaigners have warned that a crackdown by Microsoft and Google on internet searches for child abuse images will not stop paedophiles using the web to share horrific photos and videos.

The internet giants announced that software is to be introduced that will automatically block 100,000 “unambiguous” search terms which lead to illegal content.

Britain’s prime minister David Cameron hailed the decision as “significant progress” after the companies insisted that it “couldn’t be done, shouldn’t be done”.
