Is something like a reddit thread enough to arrest someone then? Even the person behind the AMA is tracked down, is that evidence enough to get him in jail?
As evidence - of course not. But as means to fin out who that is - sure, why not. Once the person is identified, it is a question of good old survelliance, and they are professionals at that, so chances are the guy will make a mistake, and sooner rather than later, and the hard evidence will be there. Look what happened to LulzSec - once the person is known, if he continues to do what he does, he will lose. Even professional spies can not pull it off if identified, what to say about some college students?
