4chan is anarchistic rule. It's capable of great deeds in the same way that a thousand monkeys with a thousand type writers will one day produce Shakespeare.
There's no real way to "harness" 4chan for good because the point of the site is that they don't give a shit about your good or evil and instead do things because they're entertaining. It's entertaining for them to fuck with a celebrity who takes himself so seriously and believes he's making a difference.
4chan's currency is lulz and they run a damn stable economy over there.
