Who is announcing bogons?

Paul Vixie did a great job with the first Real-Time Blackhole List. But people move on, and things change. But my real question is why are negative bogon lists necessary? If you ask providers, they all say they implement positive prefix list filters on all their customers. So who is injecting the bogons? And why do they still have a network connection? Should we be spending time teaching people how to do positive prefix filters, or trying to explain to them why the negative prefix filter the last network administrator installed 2 years ago is out of date. What is the cross-over point? When does the number of lines in a bogon list become larger than the positive prefix filter? If you are going to list every sub-allocation which isn't routed, why not just list the allocations which should be routed?
