I don't know how this translates to actual blacklist entries, but for
submitting complaints, blacklist operators ignore the smaller
networks, whether they are in WHOIS or not. I would also expect that
if you've got a significant spamming problem, some blacklists will try
to entice *you* to do something about it proactively. Overblocking is
often used for that purpose.
