Yes, please stop this popup as it is beyond annoying, and I feel preasured to turn it on. I have the same issue with the popup urging me to download the Yahoo app. "Not now" does not mean bug me every hour untill I say yes, or give in, and download the app so you can have access to everything on my phone.
The reason our spam filters are not working is because they are from Yahoo affiliates, so Yahoo.is not stopping them on purpose. Pathetic Yahoo.
Your spam filter is broken. I am getting many emails in my inbox that are spam, and now I spend every day re-marking up to 40 of them as spam. This is ridiculous.
