Hi all,

about what they want here, prior to standardizing anything in this space.

Apologies for the delay in responding from the perspective of a browser
vendor (Chrome)

The use case we would like to see in Chrome is to basically duplicate what
is done on the search results page for DMCA, but for DNS resolution errors
caused by legal blocking. I don't have images on hand, but on an, e.g.,
Google search results page where some results have been removed due to
DMCA, it says at the bottom something along the lines of "Some search
results have been removed due to a DMCA request. See more information at
the request at Lumen Database [link-to-lumen]".

The link to Lumen is roughly of the form
https://lumendatabase.org/notices/$id, e.g.
https://lumendatabase.org/notices/51783697.

We would like to duplicate this on the NXDOMAIN error page in the browser,
for EDE's of BLOCKED or CENSORED. Lumen Database already has information
about legal requests that block the resolution of certain names in certain
regions, and graciously allows us to link to them. The current plan is to
use Mark Nottingham's Public Resolver Errors draft to do so. We see the
preregistration of link URLs to resolver names as a way to mitigate the
risk of allowing arbitrary attacker controlled user-facing messages on
error pages.

We don't have any real stake in any specific approach, other than:
- We want to render a link
- We do not want to be able to render arbitrary links
- We do not want to render arbitrary attacker-controlled strings in
otherwise trusted UI.
