I don't buy that once IP space has been used by a spammer it's ruined
forever. Only if abuse complaints are ignored for a considerable time are
the IPs likely to end up widely privately blacklisted. Even then, I don't
believe "space is widely blacklisted, please give us more" is a valid
justification for going to ARIN for more IPs.
We've terminated spammer customers...and reused their assignments.
