As others have pointed out Madoff might not be a solid example as it was a single firm committing fraud vs the possibility of multiple actors abusing a bubble (and possibly committing fraud as well).
It might be closer to the abuse of sub-prime mortgages and mortgage-backed securities. Is feeding a bubble the same as pumping and dumping? Sure can be.
