This seems to contradict your statement below (that being 'All of them
are just and only lists, evidences of dynamically assigned addresses.
They do not indicate mail received from them is spam'). If that statement
is true (and, IMO, it is) then an IP being dynamic does not hinder in
the detection of spam.

Fatal flaw with blacklists. In the end you wind up shooting the innocent.

nuclear weapons.

They are neither just nor unjust. They are lists. The use they are put
to and the care with which they are maintained can be just or unjust.
IMO the use they are put to is unjust as they are utilised to punish
those who have done no wrong.

As someone who receives well over 1000 pieces of spam a day I find the
above does not make their use in the manner spacified as just.
