There are sizable chunks that are fairly quiet (un-interesting numbers, luck of the draw, etc). Given that its mostly mis-configurations, laziness, ignorance, or poor planning... I suspect the worst ranges will need to be sacrificed, and the remaining 80-90% of the space used for legitimate allocations. Unfortunately, anyone who accepts allocations in 1.x will need to be aware that they will have a slightly lower quality address-space. Accepting 1.1.1.0/24, for example, will land you with a continuous 50mbps of junk... seemingly forever... and a respectable chance that some percentage of the net will never reach you, due to their own misconfigurations.
Practical solution: Move YouTube to 1.1.1.1, Google to 1.1.1.2, Yahoo! to 1.1.1.3, Facebook to 1.1.1.4, etc. Maybe someone at YouTube was actually testing that strategy ;-) ...
