Its not a "technical" problem in that a smtp block or a nullroute
solves it for you

Now picture what happens when the ISP turfs whatever spammer got a /14
from them, or the RIR revokes a /20 that is full of malware C&C .. and
then, months later, its reassigned to someone else.

I would invite you to go explain how easy or difficult a technical
problem it is, to whichever poor SOB gets that netblock.
