Serious spammers have many more IPs than mortals can imagine. A spammer contacted a friend of mine who runs an ISP a couple of weeks ago, and he wanted to rent "several Class B nets". A Class B network has 65534 IP addresses. So this spammer wanted more than 100,000 IPs from one ISP. He's probably spread his "business" across many ISPs, as well. My friend refused to do business with him, of course. In a way, I'm glad IPv6 is going nowhere...
