Twitter on Thursday permanently suspended the Twitter account of David Duke, the former leader of the Ku Klux Klan.

Duke's account has been active since 2009, according to an archived version on the Wayback Machine, and had more than 53,000 followers.

Activist account Sleeping Giants first spotted that Duke's account had been suspended.

A Twitter spokesperson confirmed the suspension to Business Insider, saying the account has been "permanently suspended for repeated violations of the Twitter Rules on hateful conduct. This enforcement action is in line with our recently-updated guidance on harmful links."
