doubleclick opt-out doesn't work

I've been playing with settings and techniques for minimizing the amount of data gathered about me online. DoubleClick is probably the most invasive, as it silently tracks you as you wander the web, quietly recording what you do, and how you got there, as part of Google's advertising distribution network.

It has an [opt-out policy](, and they provide a page with a link that is supposed to set a cookie to flag you as opted out - verboten for tracking - but it doesn't seem to work. I've got the opt-out cookie set, but every day, I have fresh cookies from DoubleClick, waiting to be deleted.

What part of OPT OUT does DoubleClick not understand?
