The social networks committed at the end of last year to a code of conduct, according to which they would remove hate speech on their platforms within 24 hours of being notified of it. The recent data shows that the companies have mostly stepped up their efforts, Reuters reported.

Facebook reviews flagged content in less than 24 hours in 58 percent of cases, an increase from 50 percent in December. For Twitter, the current figure is 39 percent, up from 23,5.

According to the New York Times, Twitter still falls short of the goal of removing 50 percent of hate speech on its platform.

YouTube, however, is now less effective than in December, having gone down to 42,6 percent from 60,8, according to Reuters.

Overall, the companies remove twice as much content now compared to the end of last year, deleting content in 59,2 percent of cases as opposed to 28,2 percent in December.
