About the question who knew what: I have deleted the email dump, but while I was skimming it, I did see an email in -- August? if not August, then late July or early Sept. -- from Josh Garza to Joe Mordica, with the subject line 'Dan Pease'. In it, Garza basically says: whoa, did you actually tell Dan Pease how our "mining" works? [Scare quotes mine, of course.] Mordica says: yes, he said you wanted me to. Garza says: well, yes, I wanted you to fill him in a bit, but not *that* much. Do NOT do that again!
Since Dan Pease was pretty heavily involved, the idea that he didn't know that the mining was virtual, and that Garza was horrified to learn that he'd been told, says a lot. On the other hand, what it does not say is that Joe Mordica didn't know.
I believe that was Capuano, not Mordica, IIRC.
It was Mordica. From July 27. Josh Garza: (Subject: Dan Pease): "He said you explained to him how zenminer works?"
Joe Mordica: "Yes sir. He said you wanted him involved enough to run it. Is this correct?"
JG: "I did, but I never told you to tell him.
Things are fine, but I want you to know for the future. Disclosing confidential information, even to another staff, is in breach of our confidentiality. Do yourself a favor and just to don't talk to anyone with out specific direction from me to do so. I don't want to have an issue

"
JM: "Sorry about that. I now understand the scope of the situation. If it was anyone but Dan I would not have. But now I see what your saying. Thanks for letting me know this way."
JG: "It's good
