Twitter Inc on Thursday permanently banned U.S. conspiracy theorist Alex Jones and his website Infowars from its platform and Periscope, saying in a tweet that the accounts had violated its behavior policies.

"As we continue to increase transparency around our rules and enforcement actions, we wanted to be open about this action, given the broad interest in this case," the company tweeted. "We do not typically comment on enforcement actions we take against individual accounts for their privacy."

In a video posted on the Infowars website on Thursday Jones said, "I was taken down not because we lied but because we tell the truth and because we were popular."

The ban came weeks after Apple, Alphabet's YouTube, and Facebook took down podcasts and channels from Jones, citing community standards.

Jones, whose conspiracy theories include that the 2012 Sandy Hook school massacre was a hoax, hosts the syndicated radio program "The Alex Jones Show."

Last month, Jones lost a bid to dismiss a defamation lawsuit brought against him by the parents of a boy who was killed in the Sandy Hook shooting.

On Wednesday, Jones attended a Senate Intelligence Committee hearing on ways to counteract foreign efforts to influence U.S. elections and political discourse. Facebook Chief Operating Officer Sheryl Sandberg and Twitter Chief Executive Jack Dorsey testified at the hearing.

Twitter said on Thursday that it would evaluate any reports regarding other accounts potentially associated with Jones and Infowars.

Last month, Twitter banned Jones and Infowars for seven days, citing tweets that it said violated the company's rules against abusive behavior, which state that a user may not engage in targeted harassment of someone or incite other people to do so.
