I agree with Paul's comments in their entirety, but wish to emphasize
this point in particular.  An IP address emitting spam is declaring
its hostility; it's prudent to presume that it may, at any time,
begin to emit other forms of abuse or attacks.  It's therefore reasonable
to treat it as an enemy -- because it is, and moreover, it's done us
the favor of overtly declaring itself so.
