Pyramid schemes are on the rise – but do those who join up deserve prosecution or compensation?

Let’s say we invite you to invest £1,000 in our new and brilliant business. We promise you an impressive return on your money, and all we ask is that you persuade a few of your friends to invest the same amount. They in turn will need to find some more investors. But remember, we’re all in this together, and everyone will end up richer.
