As this thread has highlighted, some people filter/block based on random variables: the covering / 24, the covering aggregate announcement, and/or arbitrary bit lengths. If a particular server is within the scope of what someone decides to filter/block, it gets filtered or blocked. Good SWIPs/rwhois entries don't mean jack to those admins.
Well it means something to me. I'm not one for widely cast blacklists but for something like a series of IP addresses all spewing spam from I will often put temporary /24 filters in place if I'm unable to determine exactly where the actual block boundaries are. If the addresses are SWIPed/rwhois then that is much easier and there is no need for such a wide net.
