I've seen those unremovable sponsored posts at the top of the box. Even clicking on them to hopefully trigger some response doesn't work, they won't go away. I don't use Yahoo mail much because they won't let you download your email into a resident program like Thunderbird unless you pay an annual fee, and even then I don't think it makes a difference on the number of ads you see.

Yahoo is busy trying to reinvent themselves these days. They own Flickr and have removed all pretense of customer service, so they don't get any kudos for that, but they did hire David Pogue as their technology adviser and reporter and I've always enjoyed his work.
