"Apparently these people are sufficiently powerful that taking down a few useless sites can get the FBI to put together probably a multi-million dollar investigation." You, nor 4chan, decide what is useful or useless. While I might empathize with the anger and outrage over certain things (like the absurd judgments meted out to copyright violators), lawlessness is not cool. All 4chan and friends are doing is guaranteeing stricter, even more draconian internet controls. And at the end of this a couple of dumb teenagers or young adults -- caught up in the group sense of invulnerability -- are going to get sent to prison. Which is just stupid all around, but it's the result of dumb actions like this. Worse still, as with many many actions like this (see also: War) it's a couple of people who put themselves at no risk that encouraged others to carry out the venture.
