After weeks of controversy, Twitter officially banned conspiracy theorist Alex Jones and his InfoWars site from its platform. The social media company tweeted out the decision from its Twitter Safety account Thursday afternoon, stating that it permanently suspended Alex Jones and InfoWars after both accounts posted tweets and videos that violated the company's abusive-behavior policy. Previous violations also contributed to the decision to ban both accounts.

Today, we permanently suspended @realalexjones and @infowars from Twitter and Periscope. We took this action based on new reports of Tweets and videos posted yesterday that violate our abusive behavior policy, in addition to the accounts’ past violations. https://t.co/gckzUAV8GL — Twitter Safety (@TwitterSafety) September 6, 2018

Both accounts show "account suspended" messages, so the tweets and videos that violated Twitter's policy are no longer available. However, according to a report by The Daily Beast, Twitter confirmed that one of the videos that violated its policy was an InfoWars video posted to Jones' Twitter account. It showed Jones verbally attacking CNN reporter Oliver Darcy, saying, among other things, "Those are the eyes of a rat."

Last month, Twitter gave Jones a small punishment for his inflammatory behavior on the platform—a one-week suspension that prevented Jones from tweeting or retweeting from his personal account. That came after users flagged a video that Jones posted to Twitter in which he encouraged his supporters to ready their weapons against the media and other groups.

Twitter's first punishment was minor compared to the repercussions that Jones and InfoWars faced from other tech companies just days before. YouTube, Facebook, Apple, Spotify, and others had removed content made by Jones and InfoWars from their respective platforms. Facebook followed up by suspending Jones for 30 days, while YouTube terminated his account after it found Jones violated the company's Community Guidelines.

Twitter faced a lot of pressure from users to take action against Jones before the company issued that one-week suspension. At the time, CEO Jack Dorsey said that Jones hadn't violated Twitter's policies but that the company would continue to monitor him and take action if he did so.

Twitter now joins YouTube as a social media platform that won't have anything to do with Jones or InfoWars. The permanent suspension blocks Jones and InfoWars from their combined 1.5 million Twitter followers, which adds to the numerous supporters that now can't follow Jones' and InfoWars' content on other platforms thanks to previous bans and punishments.

The ban comes after Dorsey testified before Congress on Wednesday about political biases and alleged election interference. At one of the sessions, Dorsey denied that Twitter had any biases against conservative voices after Republican lawmakers repeatedly brought up the subject.
