Twitter has removed some accounts thought to be used to circumvent a ban on conspiracy-monger Alex Jones and Infowars, the company said Tuesday.

A Twitter spokesman confirmed that the accounts had been removed but provided no additional comment. The company says it usually does not discuss specific accounts.

Twitter permanently suspended @realalexjones and @infowars from Twitter and Periscope in early September, later than many other tech companies such as Apple and Facebook. It said it based that action in reports of tweets and videos that violated its policy against abusive behavior.

The ban underscored the difficulty many social-media services face in trying to consistently apply their rules against harassment and other bad behavior. It was also likely from the start that Jones and his supporters would find ways to get around Twitter's ban by setting up new accounts or posting from existing accounts that were not part of the initial purge.

Twitter said Tuesday it would continue to evaluate reports regarding other accounts potentially associated with @realalexjones or @infowars and would take action if it finds content that violates its rules or if other accounts are used to try to circumvent their ban.

As of Tuesday afternoon, an account for Alex Jones podcasts was still up on Twitter, as was another called "InfowarsFeed" that hasn't tweeted since 2008.

Other tech companies, including PayPal, YouTube, Apple and Spotify, have limited or banned Jones' activities on their sites.

Infowars has said the moves are intended to sabotage the site just weeks before the midterm elections.

On Twitter and elsewhere, Jones has done such things as describe survivors of a shooting in Parkland, Florida, "crisis actors" and saying the mass killing at Sandy Hook Elementary in 2012 was fake. He had about 900,000 followers on Twitter. Infowars had about 430,000.
