So I'm certainly not going to give recipients of the extra money scammer tags at least until Nefario releases most of the BTC and asset info.
Its ok not to trust nefario but what you are saying will actually lead to the point were nefario wont give out any more payment nor the assetinfo.
I vote to put all the double payments in a legal fund to send Nefario to the jail where he belongs. Moreover I will donate all my GLBSE assets to the first convict who rapes him.
