For anyone who's participated in forums, online games, or any other system where you can communicate with random strangers, you've probably encountered people who make you angry. Some are just people who you don't get along with legitimately, and some are "trolls"; people who toy with others for their amusement.
What makes people trolls is generally the anonymous nature of the Internet. Sadly, this is often a perceived anonymity only. Just yesterday, I found a post I didn't agree with and wanted to comment on it. Since the author had locked comments, I did a little web research and found her real name, school, e-mail address, and other sites she posted to. I was only looking for some means to contact her, but the information was fully filled out on these sites with no protection at all.
Imagine her shock to find out how easily she was found (and to be honest she called me quite a few names at first though we did have a good conversation after that).
Sadly, most people don't realize how difficult it is to be truly anonymous. The only things keeping you safe in many cases is that you've never given anyone enough reason to look you up. And now we get to the real story.
Online games can be tense and frustrating. For example, the first time I played an online competitive game, I was completely crushed in seconds and insulted repeatedly for my efforts. I chose to stick with offline gaming but others weather the storm and build their skills to the point they can keep up and even be good enough to win.
However, there are just going to be times that someone is better than you. That's frustrating enough, but when they're rude and insulting, it can be maddening. And for context, understand that the people who are the rudest are often younger males who believe they don't have to "pull any punches" since they don't have to face the consequences of their actions (an idea that was excellently portrayed in Disney's Pinocchio).
My point is, this kid was being an ass with abandon. What was his opponent going to do? Hunt him down and hurt him? Turns out the answer was yes.
And believe it or not, there's a lot of support for the attacker online. The sad fact is that there are still consequences for what we do, even if we're online. Similar to the adive every parent must give to their children of how posts last forever, we must also teach our kids not to draw undue agression. After all, how do you know whether the person you're "Teabagging" has the ability and desire to come after you in person?
