> Does your browser unblock 3rd parties that promise to honor Do Not Track? no

Why does that get a fail mark? In my opinion such promises are worth absolutely nothing. Does that compromise my anonymity somehow by disabling them?

I don't think the fail mark in that case is supposed to mean you're easier to track; it's rather related to the EFF's position on DNT:

"Setting your browser to unblock ads from websites that commit to respecting Do Not Track rewards companies that are respecting user privacy, incentivizing more companies to respect Do Not Track in order to have their ads shown at all. By preserving privacy-friendly ads, sites that rely on advertising funding can continue to thrive without adjusting their core business model, even as they respect users’ privacy choices."

Claiming you're not protected because you've decided to block all does seem deceptive, though.
