[tech-whois] A follow up session in San Francisco?

[Michael Young]

Absolutely, a user ID accessing a whois system does not have to be tied to
known identity if the overall policy supports anonymity.  The elements of
usage enforcement can be applied against the user ID just the same.  Of
course you would want some control heuristics preventing the automated
creation of those anonymous user ID's in any sort of scale, but that's a
well understood problem with many existing tools that can help with that.

Michael you raise an excellent point re: IPv6.

I also think you touch on important benefits of "knowing the source":
accountability and auditing. Anonymity is very different from accountability
but the Internet fails to make this distinction and thus abuse flourishes.

There are several forms of authentication that can provide auditing or a
basis for rate limiting that do not require disclosure of personal
information or creation of an identity, e.g., guest accounts that can be
bound to sessions, connections, validated origin IP addresses. There's a lot
of room between "unknown origin, unknown querying party" to "non-reputiable
originator of a request".
