The only thing that can be done is just have the feature appear as a list without the images, I am personally not in favor of having features in the beta testing phase to be removed. I like seeing new things implemented to enhance the user experience.
All in all, if you don't like it, install adblock for your prefered browser and you'll never see it again. I am going to mention that, as a reminder, Steve did say that it is "learning", so it will be a matter of time and patience, so there should not be much to worry about. And I have a feeling that it is just going to be showing threads from the ROM Hacking Hub Section, as it is the forums most popular section.
