I have no idea who you complain to but their pop up and pop over ads are putting me right off yahoo, and that's before being even more nauseated by pumping hearts etc. I no longer use yahoo as my main email provider because of this, but it's also all over answers, just as you're trying to read a question you're getting ads in your face, pop ups pop downs it's beyod a joke. But that's not all you should be concerned about. If I asked you to join my website offering all sorts of services such as email and video sites and pic sites etc, all for free but on condition that you allow me to spy your pc and collect data such as what operating system you use, what screen resolution you have, which site you were at before coming to mine, your ip address, the name of your pc, and everything you do on the internet, would you join my site? Most likely not, but when you sign up with yahoo they tell you that by signing you are agreeing to their privacy policy which tells you that is exactly what they are doing. Аnd then they have the cheek to splash ads all over our screens.
