Both [of "Broadband IP space" and "IPs used for email marketing"] could be true, although that would probably be the best choice. However, as we approach the point where obtaining IPv4 address space becomes more difficult I think we will have to accept that individual IPv4 addresses will share role much more frequently.
I guess. But the allocation policies, whois requirements etc remain substantially the same for ipv6.
This similarity should make less and less sense, as time goes by. How do users choose between IPv4 and IPv6 in case they have both? In particular, DNSBLs are more difficult with IPv6, so it could make sense to kindly push users to sticking to IPv4 for _and only for_ tasks that may benefit from DNSBLs, typically public MXes and email marketing.
I have no problem with blocklists ipv6. Larger chunks however :-) I do have problem with abuse, where spam is the dominant factor, often used as vehicle for other kinds of fraud.
