Twitter suspended more than 50 accounts operated by white nationalists Friday amid criticism over its handling of inflammatory posts on its platform.

“The accounts in question were suspended for violating our policies in relation to violent extremism,” a Twitter spokesperson said in a statement to The Hill.

The move comes after Twitter and YouTube were singled out in a report released Tuesday by the Global Project Against Hate and Extremism that accused the platforms of allowing white nationalist groups to disseminate their message and garner new recruits. 

The report specifically identified 67 Twitter accounts, which  had nearly 140,000 followers in total, who were members of the Identitarian movement, also known as Generation Identity, which is based on the idea that immigrants are overtaking people of European descent. 

One of the suspended accounts belongs to Martin Sellner, leader of the Identitarian Movement in Austria. 

“It is another act of censorship of freedom of speech,” Sellner told NBC News, which was the first to report on the suspensions. “We are the only group really talking about mass immigration and population replacement. The mainstream has no answers to our question: Why should we accept becoming a minority in our own countries?”

Several social media companies have been the focus of intense scrutiny over their handling of inflammatory content on their platforms amid a national reckoning over systemic racism and police brutality that was sparked by the killing of George Floyd in police custody in Minneapolis in May.
