RE: Poll text call: final text by 28 September

Chris,

If 'industry attribution metrics' are collecting mouse movements and page visibility and page rending details from the user agent then this would most certainly qualify as data collection under DNT.  Further it would not qualify for a permitted use: 6.1.2.5 "A third party may only collect, use, and retain for permitted uses information that a user agent necessarily shares with a web server when it communicates with the web server...".  Mouse movement and page rendering would hardly qualify as 'necessarily shares' - this is state covertly leaked.  If a user has expressed DNT:1 then 'industry attribution metrics' implemented by a third party are definitely not permitted.

The difference is that in this case users can probably take control by securing their UA with an extension that blocks 'industry attribution metrics' so they may not need to depend on DNT being respected.

cheers
Fred
