Facebook on Monday removed four pages belonging to U.S. conspiracy theorist Alex Jones for "repeatedly posting content over the past several day" that breaks its community standards.

The company said it removed the pages "for glorifying violence, which violates our graphic violence policy, and using dehumanizing language to describe people who are transgender, Muslims and immigrants, which violates our hate speech policies."

"Facebook bans Infowars. Permanently. Infowars was widely credited with playing a key role in getting Trump elected. This is a co-ordinated move ahead of the mid-terms to help Democrats. This is political censorship. This is culture war," Infowars editor-at-large Paul Joseph Watson tweeted.

Since founding Infowars in 1999, Jones has built a vast audience. Among the theories he has promoted is that the Sept. 11, 2001, attacks on New York and Washington were staged by the government.

Most of Jones's podcasts from his right-wing media platform Infowars have been removed from Apple's iTunes and podcast apps, the media news website BuzzFeed quoted a company spokesman as saying on Sunday.

An Apple spokeswoman said in a statement that the company "does not tolerate hate speech" and publishes guidelines that developers and publishers must follow.

Also, Spotify, a music and podcast streaming company, said on Monday that it had now removed all of Jones's Infowars programs from its platform. Last week it removed just some specific programs.
