I know that everyone in the world today wants to know pretty much everything (possibly more than one's spouse) about everyone.

Does Stack Exchange have an official policy on honoring Do Not Track browser settings?

FWIW, my browser settings clearly say:

Tell sites that I do not want to be tracked

However, upon navigating to any of the SE sites, it's evident that Do Not Track setting isn't being honored.

Privacy Badger browser extension from EFF tells me that I am being tracked:

Moreover, on http://stackoverflow.com I see some more sites doing the same:

http://qa.sockets.stackexchange.com
http://engine.adzerk.net

I understand that there is no legal requirement to honor the setting. I just wanted to understand what is the public stand that Stack Exchange takes in this regard?

The Privacy Policy, as of now, doesn't answer this question.

EDIT: One of the comments claims that it's not Stack Exchange but the advertisers who are tracking. While one of the SE sites http://qa.sockets.stackexchange.com happens to be on the list of those that are attempting to track the user, the others are advertisers. Why can't Stack Exchange ensure that it's advertisers offer a mechanism of tracking opt-out?

It's funny to see that those contributing under cc-by-sa are tracked by Stack Exchange and/or it's advertisers without any clear word about the policy.
