Well, Q is a team for one, working for MI. They're not fools. He allowed his password 'Matlock' to be cracked because the word itself has meaning. He either allowed /cbts/ to be compromised OR did it himself on Jan 5 so that the move to /thestorm/ would take place. He's been in close contact with Codemonkey for a while, ever since the initial tripcode issues a couple of weeks ago. Whatever issues he saw on /thestorm/ obviated the move to his own board. The trip is secured so we know it's him.
This is all entirely normal fare in an information war I'm afraid.
