We had proposed a resource link to accompany the returned value so users can learn more as to why their particular DNT signal was not accepted (this could include not only the explanation but also instructions for the user to register a valid preference setting).

I do not agree with the value being "T" as this is short for Tracking which is not yet been defined so I would recommend we use "I" for Invalid instead.

Rigo:  Users require substantive information on why a server believes there is non-complaince--not a mere "T."  The W3C process needs to ensure that users have robust information on the real reasons why their request is being rejected--such as Yahoo, major advertiser members of ANA, and  [fill in the blank] don't believe a browser should create a stronger default for DNT.

We cannot leave it to the regulatory process. or blocking tools.  The Spec should signify precisely why a UA is rejecting the user's request--especially when it is doing it for its own narrow economic purposes.  This should be on our agenda when we speak next.

it looks like there is a consensus between Roy, Shane, Me and some others that
if a server believes a signal is non-compliant and does not want to honor, it
responds with an appropriate status (I suggested "T" with a definition)

The pressure to honor DNT:1 will not come from the Specification IMHO. Users
are concerned and will use browsers that will react on a site not accepting
their DNT request. From my research, I still have some sandbox where I can
show you how far this can go. For the industry, not honoring carries two
risks: 1/ regulator action (deliberately general wording) and 2/ blocking

We can't anticipate and set the content of all communications, we have to set
the conduits of those communications.

There was consensus around the idea that a compliant UA would represent the

do if it receives a facially valid DNT:1 from a browser that the server
believes to be noncompliant...
