In a statement posted on its website Wednesday, Reddit announced it is shutting down several neo-Nazi forums that promote violence, sending a signal that it’s cracking down on violent content in a way that it hadn’t done before.

“Going forward, we will take action against any content that encourages, glorifies, incites, or calls for violence or physical harm against an individual or a group of people,” the popular website wrote. “Likewise, we will also take action against content that glorifies or encourages the abuse of animals. This applies to ALL content on Reddit, including memes, CSS/community styling, flair, subreddit names, and usernames.”

The announcement came just hours after a Daily Beast exposé about a prominent Trump-loving Redditor who fatally stabbed his own father after he called his son “a Nazi and a racist.”

Among other neo-Nazi communities, Reddit has shut down /r/pol,/r/nazi, and /r/DylannRoofInnocent.
