Yahoo Yellowpages Sponsored listing = murder on Yahoo search results?

[skysxx]

Last night, I checked our website listing in Yahoo Search and we came up three times. I decided it was time to market our physical store front in Yahoo Yellowpages Sponsored listing which allows you to add a link to your website in addition to your address and phone number.

This morning, I wake up to find our sponsored listing active but when I search for our site in Yahoo Search, its gone. No reference whatsoever.

Does Yahoo pull your website out of it's search results as soon as they know you are willing to pay for placement? I'm thinking this is one of their marketing strategies aimed at small businesses to get you to sign up for Overture, etc.
