We are discussing two different issues here. First is, I support that servers should give the users a clear answer wether their DNT request is honored. There should be an option to answer NACK. Second is, a company claiming "We will honor DNT when it's coming from the following user agents" or "We will honor DNT from all user agents except for the following" (I am quoting Ian's example here) is honest - and I appreciate that. But whether it is "compliant" to the DNT recommendation or not, is up to us as a working group. It is our task to discuss whether we want the spec to allow this cherry-picking. (Don't get me wrong, companies can stll do so. But will they be able to claim DNT compliance?). I oppose this. I think the spec should state that when you receive a valid signal, no matter from what UA, you have to honor it in order to claim DNT compliance. There are several reasons for this: 1) predictability David raised this point and I agree: "Defining that "I'll stop tracking unless I don't feel like it" as *compliant* makes it basically unpredictable what will happen." 2) only for "uncompliant" UAs? If we open the spec to cherry-picking. Will it stop at "uncompliant"? Or will the spec just stay silent or explicitly allow for other motivations? Patent lawsuits, harming competitors, just feeling like it - for painting a very black picture. I don't support this as being considered DNT compliant. 3) Who decides wether a UA is "uncompliant"? As long as there is no judgement by a competent authority, this is a very critical statement. 4) liability issues If the spec allows to NACK the DNT requests of "uncompliant" UAs, and I site claims to "honor DNT from all user agents except for the following ..." it makes a legally relevant statement about these UAs. Which may lead to liability and claims for damages by these UAs if the judgement is wrong. If the spec is more open -> issue 2. 5) hindering privacy-by-default The proposed Data Protection Regulation of the EC explicitly asks for privacy by default.
