Writer Lindy West, who spent years cultivating a reputation for engaging with social media trolls, has announced she’s leaving Twitter because of the “global repercussions” of the platform’s “refusal to stop” harassment campaigns launched by the white supremacist, misogynist “alt-right” movement. In a January 3 opinion piece at The Guardian , West explained that she had deactivated her Twitter account after “half a decade of troubleshooting” to curb personal harassment and threats from anonymous users trolling her on the social media platform.
