If you’re on Twitter, there’s a good chance you’ve seen hashtags like #CuttingForBieber, #CutForBieber, and #Cut4Bieber spreading today, along with some disturbing pictures self-inflicted bodily harm.

Complex revealed that the cutting hashtag was sparked by theĀ 4ChanĀ board, where users sought to “get some little girls to cut themselves” by posting pictures of cutters on fake Twitter accounts and claiming that it was being done to get Justin Bieber to stop smoking weed. There’s even a set of instructions for how to spread the news on Twitter, Facebook, and fake news sites.

Sick stuff.

UPDATE: There is now a Cut4Bieber.com.
