Facebook “is at risk of committing a criminal offence” in the UK after a Times investigation uncovered potentially illegal terrorist and child porn content on the social network, despite moderators being made aware of it.

Using a fake Facebook profile, a Times journalist was able to befriend more than 100 supporters of terrorist group Isis (Islamic State in Syria) and join groups sharing “lewd or pornographic images of children”.

The story was published on the paper’s front page today and follows days after Press Gazette launched its campaign calling on Facebook and Google to stop destroying journalism.
