Ok, so I dug around a bit and found this:
http://docs.yahoo.com/info/privacy/us/yas.html
and following the link I found this:
http://www.omniture.com/2o7
it gives you the option of them placing a new cookie which (they say) will prevent my data from being sent out, but it does not tell me what program on my computer is wanting to send out the data in the first place.
Pretty fucked up if you ask me to allow a third party tracking cookie that BLOCKS NEW ADVERTISERS FROM JOININGGGGGGGGGGG!!!!

Enjoy. I know I have.
