John, I respectfully disagree. Servers should not be placed at an automatic disadvantage if they receive conflicting signals. Unless there is a singular, consumer driven signal, then no signal should be considered to have been received. Its disingenuous (in my opinion) for consumer advocates to on one hand agree that users should have to expressly activate DNT and then on the other hand suggest that non-compliant or conflicting signals must be honored. You're either on one side or the other - straddling the fence in this manner is not helpful. - Shane From: John Simpson [mailto:john@consumerwatchdog.org] Sent: Wednesday, October 10, 2012 3:22 PM To: Shane Wiley Cc: Jonathan Mayer; public-tracking@w3.org Subject: Re: Multiple DNT Headers (ACTION-283, ISSUE-150) Shane, What would be the reason for acting as if no DNT header had been received if they conflict? I'd think if there were a conflict, the consumer/privacy friendly approach would be to assume the user meant to send DNT:1 and somehow misconfigured the UA. In other words, proceed with caution until you clearly determine what the user intended. That's why the best practice would be to inform the user of a possible problem. Best, John ---------- John M.

It is a best practice for the server to alert the user about possible user agent misconfiguration.
