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. -- Suresh Ramasubramanian (ops.lists@gmail.com)
