For what it's worth, I'm now personally convinced that BurtW was himself convinced that Pirate was not running a Ponzi scheme or similar scam. He's actually a good example of why I think most PPT operators deserve a "free pass" for the Pirate fiasco.
It is absurd to suggest that a reasonable person could accept that it was anything other than a scam. If a PPT operator didn't know, then they should have know and are negligent. This standard applies once you take an active role, as they did. Those who solicit money, fabricate credit ratings, promote or shill for the scam bear a greater share of culpability. A free pass would be a mockery of justice, if that matters at all.
