The cyberbullying epidemic has the global attention of countries and their governments. In fact, the new breed of bullies is narcissistic and they treat the internet as their own personal stage, with an audience of thousands. Narcissists’ aggressive reactions when combined with the anonymity of the internet, can provide a forum for them to become cyberbullies. For example, a narcissist who has received negative feedback at work or school is more likely than a non-narcissist to react with aggressive online behaviour, and act antagonistically toward the person who provoked him, or even towards an innocent co-worker or classmate in a forum which will allow his aggression to be anonymous.

Teens can be mean through technology away from the adult gaze
“Trolls” on social media are an increasing phenomenon. Like their mythological counterparts, internet trolls are nasty creatures who are attention-seekers; their goal is to wreak online havoc for the purpose of ‘fun’. Internet trolls thrive on weakness, naiveté either real or imagined, and also feast off the emotional reactions of their victims by insulting, upsetting, shocking and provoking users. Trolls and their kind have a code of irresponsibility, and aside from disrupting online communities, have been known to hack into social media profiles and perform pranks. An example of this is when a troll hacked a MySpace memorial page of Mitchell, a teen who had committed suicide. The troll replaced the boy’s face with the face of a zombie, then posted the victim’s face onto hard-core porn scenes, made videos re-enacting the boy’s death and made prank phone calls to the boy’s parents with greetings such as, “Hi, this is Mitchell, I’m at the cemetery”. This online behaviour probably wouldn’t happen if the perpetrators had to deliver their messages in person—evidence again of the ways in which social media is enabling disturbing behaviour in its users. The technology reduces any social barriers and this behaviour, under the guise of fun, exists only under the conditions of distance and anonymity.
Don’t tolerate the “I was only joking” cop-out. There’s nothing funny about saying or doing mean things.
My take on it: Trolls are cowards.
Because trolls delight in reaction, ignoring them is the best way to disempower them and the acronym DNFT on social networking sites, stands for “Do not feed the trolls” meaning do not engage in dialogue to give them further ammunition. Engaging with trolls by defending yourself can be counterintuitive.
