And why would blocking the /24 be appropriate instead of matching the registry?

I would refer you to the huge number of netblocks out there that stay at /16 or larger size, with the upstream not SWIP'ing or otherwise delegating netblocks in APNIC (or wherever, such as an rwhois server) as they provision IPs.
And I refer you to the blocks which are properly registered down to the /29 level and
you are saying that if you are a good citizen collateral damage is recommended
regardless because antispammers are either lazy or technically incompetent
or like their ego boosted by intentional collateral damage?
