In the pre-internet era, news of teenage indiscretions might travel around the high school hallways. Now they are broadcast to the world. Too often, the cyber-bullying of vulnerable teenage girls leads to self-mutiliation or even suicide. Two teenaged girls recently killed themselves after posting heart-wrenching messages on social media. On the flip side, another teen might have been saved by the online activist group Anonymous, who stepped in to defend a 15 year-old girl from cyber-bullies and trolls.
