Re: Issue-207

If this is already addressed in TPE, do we need to address it in TCS?  I suppose I don't object to it both places, but not sure it's necessary.

TPE currently says:

A tracking status value of D means that the origin server is unable or unwilling to respect a tracking preference received from the requesting user agent. An origin server that sends the D tracking status value MUST detail within the server's corresponding privacy policy the conditions under which a tracking preference might be disregarded.           

. . .

This specification is written with an assumption that the D tracking status value would only be used in situations that can be adequately described to users as an exception to normal behavior. If this turns out not to be the case, either the server's decision to send the D signal needs re-examination, or this specification, or both.

A key element, addressed in the TPE is that Tracking providers should not ever have to second-guess a user's expressed Do Not Track preference. It is fair to say, that users should not have to second-guess with regard to the D-signal (quid pro quo principle). Just responding with 'D' would not be enough IMHO to fulfill the quid pro quo. The user / user agent needs to know about the reason why the signal got disregarded. The party's representation MUST be be easy discoverable, clear and unambiguous. It MAY be machine readable. The guiding principle IMHO, is that transparency is key in the granular discussion between the user agent and the server to prevent e.g., discrimination based on the use of (a certain brand of) technology, or just plain arbitrariness.

Exceptions to the obligation to provide information and offer the right to refuse should be limited to those situations where the technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user. Where it is technically possible and effective, in accordance with the relevant provisions of Directive 95/46/EC, the userís consent to processing may be expressed by using the appropriate settings of a browser or other application. The enforcement of these requirements should be made more effective by way of enhanced powers granted to the relevant national authorities. "
