they support safeFrames (like a few other small sites like deviantart). ads cant set cookies at yahoo.com even if they wanted. they render in a cross domain iframe. so they cant do it even if the adserver is compromised. they are morons for not mentioning this on that announcement. basically, they are just ignoring DNT for the few in house ads that run on front page and such. which being in house, already can track you.
