"Advertisers and other third-party domains can unblock themselves in Privacy Badger by making a strong commitment to respect Do Not Track requests."

What does the dnt-policy.txt promise mean?
Posting the dnt-policy.txt file makes a promise to the users who interact with their domain. We [EFF] believe it would be a false and misleading trade practice to post the policy without the intent to comply in good faith. However, EFF is not in a position to enforce this promise or monitor compliance.
I don't want it to be a negotiation between the EFF and a website as to the state of my privacy - I want the final say in who is going to be trusted.
When you click on the plugin icon in the browser toolbar, a popup box displays all the trackers Privacy Badger has found. There is a slider next to each tracker, with three states, green, yellow and red. Red means blocked.
As Privacy Badger works, it moves the slider for a tracker when it notices it following you across domains. But you can still manually drag the slider across to Red if you want.
