Discord purged more than 1,500 servers for instances of violent extremism in late 2020, the chat client maker revealed in a new transparency report released this week.

Discord, which covers the period from July through December of last year, saw its user base jump from 100 million monthly active users in June to 140 million in December as the Covid-19 pandemic dragged on. But with more people using Discord than ever before, the company also found itself booting more users and servers off the platform.

Indeed, these deletions have overwhelmingly hit spam accounts: over 3 million accounts were deleted for spamming, followed by exploitative content and harassment. Servers, on the other hand, were more likely to be removed for their broad association with cybercrime, but the number of servers removed for violent extremism also surged in late 2020.

Discord explained that it was taking further action against militaristic movements such as the "Boogaloo Boys," one of the groups that stormed the U.S. Capitol earlier this year; 334 servers associated with the QAnon conspiracy movement were also canned. Finally, 1,504 servers were removed for violent extremism, a staggering 93% increase over the first half of the year.

This is a solid effort by Discord, but not enough to completely shake up far-right extremists. Activist group Unicorn Riot uncovered 18 servers frequented by participants in the February riots (via NPR)-and before the 2017 Charlottesville "Unite The Riot" rally, The New York Times called Discord "the alternative right's favorite chat app," and it wasn't until after that rally that Discord began taking serious action against the extremist group.

NPR notes that the transparency report also does not paint a complete picture of Discord. While the company does take official action against criminal activity and harassment, much of the platform's moderation is handled on a server-by-server basis by users who manage their own spaces.

"This, of course, is just outsourcing to some extent the highly skilled labor of moderation and community management," William Partin, a research analyst at Data & Society, told NPR.

"If you see someone harassing someone on Twitter, you can go and report it, whereas on Discord you have to be in the right place at the right time."
