Calling themselves Money, Fast, Easy and in Cash (how about that for subtle subliminals), scammers offered 150% interest, paying out millions of pesos until they built up a large client base and then promptly disappeared, leaving thousands of Colombians in the town of Popayan broke.

It might sound absurd but for rural people across the world unexposed to this kind of scam, the offer of easy money seems like a once in a lifetime opportunity. Their neighbours are rolling in the money, making more and more each week and they feel dumb to be missing out.
