What is happening to Yahoo? Are you that desperate for ad $ that you'll stoop to putting undeletable ads in the top of my inbox? I've voiced my opinion about the unsolicited singles and lubes ads in my mail box area, but this is crazy. You can only pick 7 categories in your ads management section to block or opt out altogether - and we all know what that means, don't we? Bull-friggin-ony! Get a grip, Yahoo, before you lose all of your valued users.
