I find it funny how they did it to prove the security was inadequate.
Nobody bothers to shut down online gaming services like PSN or XBL. Sure, it's happened before, Anonymous have done it, but it's not something that happens every fucking week.
The thing I find hilarious about this, is that they did it to prove the security was shit, when they were the only people doing it.

Morons. Childish morons. :3
