Sometimes all it takes is someone with a vision and a route filter.

How about this: out of the weekly routing table report and the RIR  
allocation record, a filter is created that removes unnecessarily  
unaggregated prefixes. The filter is sorted in order of decreasing  
number of prefixes filtered out. People then install the first X lines  
for whatever value of X best suits them.

This will generate a lot of pressure on the worst offenders to do
