It depends on the goals of the greylisters.  If they're using it
to pressure marginal spammers into spamming less, that's fine,
but again they're dealing with marginal spammers and not the
hard core ones.

If they're trying to block messages, there are much more
efficient ways to do that with sender IP or sender domain
since most of the marginal spammers probably are not using
zombies.  The difference in efficiency for blocking is
probably multiple orders of magnitude.
