Without getting into Sicilian poison cup arguments around "I knew they'd think that," I find it hard to believe that someone would go to all this trouble, then innocently publish their magic trick to the world in a screenshot like that.
Edit: to be clear, I'm inclined to believe Kaminsky et al that this is a ruse. I just don't think it's that ruse.
It isn't that ruse. I replicated the file that is verified in the screenshots - the ruse is that it contains an old bitcoin transaction from Satoshi rather than Sartre's writings.
