According to an investigation, Facebook and Twitter are refusing to remove provocative Islamophobic posts from across their sites in spite of alerts from anti-racism groups.
According to the Independent, many of these posts accuse Muslims of being rapists and pedophiles. The number of such posts has increased after the Rotherham sex-abuse scandal and the murder of British hostages by Islamic State (IS) militant group in Iraq and Syria.
Facebook authorities said that they had to maintain a balance between freedom of expression and having "a safe and trusted environment" but would remove any content reported to it that attacks any race.
A Twitter spokesman said that they check all the content that is reported to the company for breaking its rules.
Muslim groups have reported various such accounts and messages to the social media websites as they are derogatory.
