Fake. 

A couple different hashtags regarding Justin Bieber fans cutting themselves to get him to stop smoking weed popped up on Twitter on Monday and, yeah, basically all fake. 

The hashtags started on the message board 4Chan's which is usually pretty good at causing havoc when they put their mind to something online....

Sad part is there are so many Bieber fans who probably took the hashtag serious....not sure if there was any actual cutting, but definitely caused quite a stir by people thinking it was real. 

Miley Cyrus retweeted: "#cut4bieber? Cutting is NOT something to joke about. There are people who are actually suffering from self-harm, this is so disrespectful."
