Not that I'm really defending this policy, but sub-allocations are very often not SWIPed. I'd say 75% or more of the time I'm looking a problem IP address it is part of a /19 or larger block with no sub- allocation.
For example, I know for a fact that 22.214.171.124 is part of a netblock assigned to a business (I believe it is a /28 or /27). It is routed to them over a DS1 or similar cable equivalent. They run a handful of servers behind including public hosting a half dozen corporate web sites and a mail server. Clearly these addresses have been assigned to this business.

And Cox is actually better than some. That's only a /19. I've seen much larger blocks than this. Somehow I doubt if we pulled that with our /20 I doubt we'd have a /19 now.
