But more recently research into how "adverse events" effect emotional development suggests sustained bullying can be as harmful as physical and sexual abuse, and it's consequences just as lasting.
To me there are some really key differences with cyber bullying. Firstly, it is much harder to escape. If you're being picked on at school, you can escape it outside school, or in other social groups. The nature of social media means it's always on. And that makes users more vulnerable.

Many social scientists have also found an increase in narcissism in western culture. With it, they note a decrease in empathy.
Some believe social media is a cause of this trend. Others see it as an outcome. What is clear is the very nature of social media - without physical proximity and the ability to read physical and facial clues - means we all risk responding thoughtlessly online (I know I have).
For all the wonderful things about social media, it can also amplify the risk of bullying. It can make empathy for others harder to generate and sustain. It also makes it harder to know when enough is enough.
Ultimately the responsibility falls on all of us. Not only to make sure we protect each other from bullying, but to accept that within all of us lies the ability to respond without empathy, to feel justified in attacking rather than engaging. Within all of us lies the potential to be both the victim and the bully.
