Hi JC,

For what it's worth, my position regarding #1. is that under DNT:1 a first party could not use -- append -- any 3rd party data.

I'm not sure I understand the use case in #2.  Do you mean: A user with DNT:1 set would visit a website. As a 1st party the website could collect data about that user's visit. Later, after the user has left the site, data from a 3rd party is appended to the earlier data set?  That should not be allowed under DNT:1 either, but I'm not sure that is the use case you are suggesting. Could you please clarify what you are envisioning in #2?

Regards,
John

I don't think (in the US) there is serious consent to the current state of data append.  This is not out of scope for a robust DNT spec.

And, third parties will not be able to collect any data about DNT:1 users.  You are proposing to restrict first parties from acquiring data that is publicly available, collected with consent or offline data.  This is out of scope for DNT.
