Okay, I'm going to play devils advocate here, and that's really hard to do because I love the verdict of this case oh so very much. So here goes.
For all you people that think this kind of thing needs to spread like ebola in a blood bank, consider this: Once you can arrest people for what they post on the internet, you can arrest people for just about anything. Arrest them for what site they visit, arrest them for pictures they have on their social sites. Arrest them for the contacts they keep online. THe internet is quite possibly the last free realm of free speech and expression. We no longer have it in the real world due to the onset of politically correct speech and discrimination laws. For example, if a person from the UK were to come to the US and walk up to a man saying "I'm looking for a fag.", he could be dropped, booked, and jailed for sexual assault just on what he said. Extreme, yes, but just oh so possible when you line up a police officer and a judge who would just love to nail a guy for appearing to be gay. The internet is a safe haven where you can say whatever you want to, and so can everyone else. If I don't like what you say, I can just scroll on down, and if you don't like this post, so can you. However, in this instance of "cyber-bullying", I think it comes down to what someone else said earlier:
wordsmith said:
"Hey, there's that girl who's viciously bullied me for the last 4 years... *clicks add*"
Stupid girl...
Just as much as this "cyber-bully" is to blame, there is also personal responsability to consider. We all dealt with bullys in school; either you clocked them in the head and knocked them down a peg and then dealt with the teacher, or you ignored them and the situation resolved itself when they got bored. This isn't any different, except it's a lot easier and more harmless to ignore them.
There's my two cents.
