"It seems very likely that they're getting the same government treatment as Quakenet" is not a conclusion that can be drawn from this blog post or the leak. My understanding based on what I read is that "Anon IRC" is on its own network and QuakeNet has nothing to do with anything except apparently relishing any opportunity to publish a political op-ed. IRC servers (and their users) have been DDOSed from the dawn of time by anyone and everyone.

To put it another way - when a body is found in the woods, you don't instantly jump to the conclusion that it must have been government drones because the government is using drones to kill people in Yemen.
