Don't give any information. There is no agreement saying to get your bitcoins back you need to jump through these hoops. You don't have to submit documents like this to purchase other virtual currencies or play stock market in Second Life. This is ridiculous. You really want to give your personal information to a scammer? Let the remaining shareholders sue nefario for breach of contract and let them refund anyone's bitcoins.
I could not agree more. I will not give identity info because there's no reason to. I can continue my relationships with my asset issuers based on my high reputation that I have kept accurate personal records of what I own and don't own.
