Twitter has banned one of its most notoriously contentious voices. On Tuesday evening, the microblogging service permanently suspended the account of conservative commentator Milo Yiannopoulos, a day after he incited his followers to bombard Ghostbusters star Leslie Jones with racist and demeaning tweets.

"People should be able to express diverse opinions and beliefs on Twitter," a company spokesperson said in a statement provided to BuzzFeed News. "But no one deserves to be subjected to targeted abuse online, and our rules prohibit inciting or engaging in the targeted abuse or harassment of others."



Yiannopoulos, who currently serves as Breitbart's tech editor, has been hailed as a voice of the new “alt-right” movement. As such, he has made a living as a provocateur, continually inflaming tensions between progressive branches of the internet focused on identity politics and the fervently anti-PC segment that constantly trolls it. For years, Yiannopoulous has used Twitter not only to voice his controversial opinions, but to direct his legion of followers (388,042 at the time of this writing) toward his opponents. As a result, he's been temporarily banned from Twitter a number of times for violating its terms of service and stripped of his verified status.



But this week he went too far. According to Twitter, it was Yiannopoulos who led the harassment campaign against Ghostbusters actor Leslie Jones — an effort that inspired the SNL cast member to leave Twitter. The barrage of tweets, many of which decried Jones for being black and a woman, were the final straw for Twitter, which is working to try to solve its harassment problem.
