Facebook announced on Thursday afternoon that it had designated some high-profile people, including Nation of Islam leader Louis Farrakhan, notorious for using anti-Semitic language, and right-wing conspiracy theorist Alex Jones, as "dangerous" and said it will be purging them from its platforms.

Jones and his media outlet InfoWars had previously been banned from Facebook in in August 2018, but had maintained a presence on Instagram, which is owned by Facebook. On Thursday, Jones and InfoWars will be barred from Instagram as well.

Other people banned on Thursday include fringe right-wing media personalities Laura Loomer, Milo Yiannopoulos, and Paul Joseph Watson. Also included are Paul Nehlen, an anti-Semite who unsuccessfully ran for Congress in 2016 and 2018.

“We've always banned individuals or organizations that promote or engage in violence and hate, regardless of ideology,” a Facebook spokesperson said in a statement provided to CNN Business. “The process for evaluating potential violators is extensive and it is what led us to our decision to remove these accounts today.”

A Facebook spokesperson told CNN Business the company goes through a lengthy process and takes into consideration a number of factors before determining an individual to be “dangerous.”

The Facebook spokesperson said such factors include whether the person or organization has ever called for violence against individuals based on race, ethnicity, or national origin; whether the person has been identified with a hateful ideology; whether they use hate speech or slurs in their about section on their social media profiles; and whether they have had pages or groups removed from Facebook for violating hate speech rules.

In some instances, when Facebook bans an individual or organization, it also restricts others from expressing praise or support for them on its platforms, the spokesperson said, adding that the company continues to view such action as the correct approach. That policy may not apply to any or all of the people banned Thursday, however.

The spokesperson added that Facebook will remove groups, pages and accounts created to represent the banned individuals when it knows the individual is participating in the effort.
