It would seem to me that ARIN and its counterparts should get together and provide a "blackhole" BGP feed (the NBL?) where all packets destined for unallocated, restricted, or private space go bye-bye.
This isn't very effective because a longer, more specific prefix wins. It would immediately inflate the route table to its maximum size if the registries announced every possible delegation. It is similar to the problem with people hijacking addresses. Unless you tie it to filters which ignore prefix announcements longer than the "authorized" allocation size. Which brings us back to the start of this thread. If AS1239 and others contributed and used something like the IRR to filter announcements, the problem is simplier.
