Long story short, someone initiated a trend on Twitter called #Cutforbieber and #Cuttingforbieber.
EDIT: As expected, this was initiated by none other than our lovely internet neighors 4ch@n. Link.
However, some Bieber fans actually thought it was a real and released pictures of themselves with their wrists cutted and bloodied up.
Apperantly, this was intended to be used as a protest against Bieber smoking weed.
Well... That escalated quickly.
Sorry I had to.
