While what you say is true, it's a non-sequitur. It's possible that I have replied to someone, and it's possible that they leaked it, but that has nothing to do with classic dictionary attacks, and the fact that such is unlikely to have succeeded with the address that's been leaked.Perhaps you intended to reply to a different comment.
Edit: To those who are down-voting this - thank you for the reality check. I don't understand why you think my comment is of negative value, but it reminds me that not everyone thinks the same way.
