I wonder how many of them were thrown under the bus for cheating on the insurance broker licensing exam using Conrad's script.

In that case, I wonder if they'd have any luck with suing him, or if the onus is entirely on them for having used it? Not being a lawyer, I'd imagine this would be a civil case where they'd go after his money / stock.

Doubtful. Even if they could claim they were 'pressured' into doing so, there was no real coercion - they made the choice to not go through the process.
