There's been banner ads and "special" pop-ups even with premium before. Plus the whole "let's re-shape the forum layout to cram in more advertising banners, boxes and backgrounds" thing.
I haven't had premium in ten years or whatever, but I do notice if I'm looking at the site from a tablet or something, that the adds are intrusive enough that I literally regret viewing the page at all.
Sort of astounding google had and issue with language on forums and not with the obvious attempts at clickjacking and manipulation.
