So the question is, what *other* data might registrars publish to
facilitate identifying domains that are probably throwaways?

Name of person/company registering?

Name on credit card?

MD5sum of credit card number?

Name of registry.

As I mentioned last week (do check out the archives!) the right
way to publish this info is likely to get the registries to
release it to a DNS-based database, distributed in the same way
the RBLs are distributed.

If some registries turn out to be better at verifying real world
identity then that is information that can and should be used in
weighting spam probablilities.  Also if some registries are better
than others at keeping the DNS database updated with their info.
