Facebook is banning several prominent figures it regards as “dangerous individuals”.
The social network accused Alex Jones, host of right-wing conspiracy website InfoWars, its UK editor Paul Joseph Watson and ex-Breitbart News editor Milo Yiannopoulos of hate speech.
Louis Farrakhan, the Nation of Islam leader who has expressed anti-Semitic views, will also be excluded.
Facebook has already banned anti-Islamic UK groups such Britain First.
The latest ban also applies to Instagram, which Facebook owns.
“We’ve always banned individuals or organisations that promote or engage in violence and hate, regardless of ideology,” the company said in a statement.
“The process for evaluating potential violators is extensive and it is what led us to our decision to remove these accounts today.”
The banned group also includes Paul Nehlen, a white supremacist, and Laura Loomer, an anti-Islamic activist with a large social media presence.
In November, Ms. Loomer handcuffed herself to a Twitter building in New York in protest at being banned from that platform.
