Whoops, not sure how I missed this one. Yes, you can see two different ads in this screenshot - one banner ad and sponsored news posts. The banner ad is random, it doesn't always appear but there's always sponsored ad stories. Just using the English, Spyware and Mobile Ad filters. I'm assuming because it's a HTTPS site filtering *may* not work.
I still see both, hmmm. I'll keep messing with it and see if anything can be done (e.g. I can create a custom rule for it and try it in the user filter). Otherwise, it's not a big deal to me, I rarely use Yahoo anymore.
