Well for me the most surprising thing perhaps was just the sheer scale and sophistication of the scam industry as well as the fact that some of the victims of the scams were in positions where they should have known better and were in positions where they made a lot of damage to the surrounding community.

For those interested in the topic I’d definitely recommend listening to the Scam Inc podcast series from the Economist, it’s a great series and first 4 episodes are free to listen as far as I know.
