Who cares who they are. They may have started as "15 year old trolls" but they've developed into a group who is standing against censorship- which is an issue that is critically important right now, particularly in the Untied States, where Comcast is lobbying to get a bill passed that would enable them to filter what gets put on the internet. This, among other things would be very bad news down the road. Think about radio. TV. Every other form of media is controlled, for the most part. Major corporations control what you watch on TV- a perfect platform for fear mongering and spreading lies designed to slowly manipulate the masses into believing absolute nonsense. And it's worked. By handing over regulation control of the internet to private companies, we would be allowing the elimination of the last chance that people have of un-tampered with, public access media.
It's time someone banned together and did something to gain the public media spotlight so that they can spread the message that we're not putting up with it anymore. Whether it's 15 year olds, or seasoned network security veterans doesn't matter. Period. The point is, someone's finally getting the message out, and that might be all it takes to get people to wake up from their deep sleep.
