The point of the first question, capability of signalling, is that if
impossible,
then the question of whether there is a role for registrars is answered in the
negative, for spam. For spammers (trace), signalling is not an issue.
The point of asking if data types matter, is that one set of registries are
provisioned (allow write access with some authentication and validity check
by multile actors to some authoritative store) with character data typed data
(domain names), another set with decimal data typed data (addresses). Each is
input to distinct publication systems. Differences in the pro formas for each
are not essential, except where they present latency of response, and may be
the root cause for an incapability of signalling.
Clearly each disjoint instance of authority for a publication of a resource
of either type is capable of responding meaningfully to notice of initial
discovery of a source of spam.
Is there any benefit to making it possible for these disjoint instances of
authority to be aware of their responces to notice of initial discovery of
a source of spam?
This is a possible application of something I've been working on.
