The European Union is considering legislative measures to harmonize how online platforms like Facebook, Twitter and Google take down hate speech and incitement to violence, a draft document seen by Reuters shows.

The proliferation of hate speech and fake news on social media has led to companies coming under increased pressure to take it down quickly.

In a draft policy paper, the European Commission says there is a "high degree of variation in the approaches taken to removal of illegal content — be it incitement to terrorism, hate speech, child sexual abuse material, or infringements of intellectual property rights."
