In ARIN, you can have zero or more abuse-c contacts per object.
I don't see why that couldn't work here.

Frankly, however, I don't think that will work as well as some people hope
because I have limited faith in the automated reporting systems following
the requested convention. Someone will think that the personal response
box is more responsive than the automatic reporting box and decide that
their need for response to automated reports outweighs the providers
need to sort things into different boxes. Others will simply report to both.

Yep.  At ARIN, abuse-c is a field in an ORG object which can either be
inherited by all child objects, or, over-ridden by an abuse-c field in
a child NETWORK or ASN object. You can have zero or more abuse-c
fields in each such object. Each abuse-c field contains a handle for
a CONTACT object.

A CONTACT object is either a person or a role account.

Why would it need to be a special role object? Why not just use the
generic CONTACT object that already exists and link to it the same
way that admin-c or tech-c links to it.

For example, say you have CONTACT objects as follows:

OD19-ARIN		Person
ABXX-ARIN		Role

Then, an ORG object, for example, could have the following
attributes:

tech-c: OD19-ARIN
admin-c: OD19-ARIN
abuse-c: ABXX-ARIN

Or, I could have ABXX-ARIN in all three fields, or, OD19-ARIN, or
any other combination. If I wanted, I could create yet another
CONTACT object for any of the fields.  Simple, easy to understand,
and pretty flexible, no?

You're telling me that there are 10 million NEW spam source addresses
every day? I find that fairly hard to believe. Even so, I bet those 10 million
IP addresses don't represent 10 million unique NETWORK objects.
I don't think it takes lots of hours to store what you already retrieved
from whois in a hash with a time-stamp. The code for doing this is
well known and I suspect there are open source tools already available
that do so.

That seems fairly reasonable and I suspect would be relatively trivial
to implement.

You might have to still look at the NETWORK or ASN object and the parent
ORG object, if the child object doesn't contain an abuse-c, but, you should
never need more than two queries to build your list of contacts for a given
address range. After that, it's just a matter of querying the applicable
CONTACT objects.

Fair enough. Increasing the query rate limits or placing finer granularity
on them, btw, is not necessarily a bad idea in my opinion. Allowing you
to sign up an address for a higher query rate service with a signed
contract containing an AUP specifying you won't be harvesting the
data for unapproved purposes would also be a reasonable alternative.
