Total suspensions related to violence and terror are now at 360,000 since the middle of 2015, with daily suspensions up 80 percent since last year, Twitter said, thanks in part to proprietary "spam-fighting" tools.
The company said it has made progress shortening the amount of time that violators are on Twitter, reducing their followers and disrupting the ability of offenders to immediately return to Twitter. It said it has bolstered its team to review complaints of extremism, as well as buoyed collaborations with law enforcement, other social platforms and international nongovernmental agencies.
Rival network Facebook has also said it has a "hard line" toward terrorism and terrorists, a company leader told The Wall Street Journal earlier this year, after it removed a profile of San Bernardino shooter Tashfeen Malik. The company also, for instance, restricted 32,100 instances of a photo depicting terror victims in Paris.
The news comes after Twitter made headlines for its free-speech policies, after reporting from BuzzFeed News said it failed to block harassment for noncelebrity users. Former Twitter CEO Dick Costolo later implied the report was "laughably false," while Twitter said it would continue to make the platform a "safer place."
