No, it is not a good thing! (If we are talking about an approach like
dynablock's.)
There are two approaches to blacklisting. Spamcop and similar services
use the presumption of innocence: they blacklist only IPs that have been
reported for spamming. Dynablock uses the presumption of guilt: if you
can't afford to buy a static IP, you don't deserve to be able to route
mail directly.

Which may or may not be reliable. My ISP's mailservers are reliable
_most_ of the time -- but when they are not, they do not return warning
messages until they bounce the mail after 48 hours on the queue.
