The #CuttingForBieber campaign emerged in early 2013 following the leak of photos showing pop star Justin Bieber smoking marijuana. What appeared to be a genuine fan protest—urging followers to self-harm to pressure Bieber into quitting drugs—was actually a malicious hoax orchestrated by users on 4chan's /b/ board. The goal was to manipulate the singer's young fanbase and spark a massive media outcry. The trend quickly went viral, causing significant alarm among parents and health professionals before it was widely exposed as a dark internet prank. Today, it is remembered as a cautionary tale regarding 'raid' culture and the power of misinformation on social platforms.
