Re: DNT:1 and "data append"

David,

As I understand it, some sites take the data they have gathered as a 1st party and append to it data that they have obtained elsewhere -- perhaps from a data broker.  I'm saying that as a user I expect to engage with a 1st party site.  I understand that the site will gather data about my visit there.  What I would not expect with DNT:1 is that the 1st party site would go elsewhere to obtain data and "append" it to the information about my visit to the site.

Does that make sense?

Best,
John

Unless FedEx were *also* a 3rd party on the 1st party site, then what the first communicates to them (or anyone else, including posterity in their memoirs) is a concern for the privacy policy, not DNT.
