Great episode. The question is how to get the target audience (the people who'd be fooled by this kind of transaction) to listen to this. I think part of the problem is that people who are fooled by this sort of thing have no interest in learning about it. 

Then again, maybe people-who-can't-be-bothered aren't the audience.

Either way, thanks for the walkthrough of the investigation. It's great to hear an example of methodical analysis.
