This is a frequent problem for those who have had address space from some of the older blocks and are trying to go back and better handle. [snip]
One point you missed: without good/accurate registry data, there is no difference between "broken announcments" and "hijacked network". That is a strong operational reason to strictly follow the registry allocations, rather than the weak concern about people selling off chunks of legacy address space. I have been aware of several times when squatted, stolen, or misconfigured-into-others'-space has been caught by registry-minded filters. Specifically regarding slices of classical B-space and not yet allocated A-space.
