I feel this is a behavioral bump in the road that may disappear as my generation becomes the parental generation.
I am 30 years old. I remember a pre-WWW world (I deliberately say WWW to differentiate from chats, BBS etc, which was largely inaccessible to all but the greasiest of geeks). I have grown with the technology, and know its potential and pitfalls. My parents however have no idea of either. They got all my hand-me-down computers, they appreciated my efforts to educate them. Because I was around fro the pre WWW, analogies were easy. I knew how the postal system worked, I could easily analogise POP mail etc. But they do not know the full potential. They look up their recipes, history of [subject] info, and IMDB pages, harass and embarrass me on fakebook, but they never really matured with the technology, and never had to suffer the pitfalls. It was just suddenly there, and they shat bricks, because it was like nothing they had ever seen, and they didn't understand the dynamics. They adapted, but never understood.
I feel as my generation become the parents and out kids hit those preteen/teen years (maybe 10-15 years), the problems will go away, because we will be capable of not only being able to give good advice on troll evasion and shaming, but we will also be in a far better position to adequately monitor, and mentor, about what actually happens on the internet. We know what to look for, we know how to find it, and we know how to deal with it. Not all of my generation are savvy enough to do it, but a greater percentage of us are, as compared to the current crop of 40-50 year old who had this thrust on them by their kids demanding internet connections and fondletoys to use on them.
I feel for that girl, and her parents who were blindsided by and lost a child to a technology they had to scramble to understand. I feel for the parents of the aggressors for not knowing just how serious the shit their kids were doing. I hope and feel that my generation will be more capable than them.
