The Meereense Knot

When browsing a thread in Firefox or Chrome on my Android phone, clicking page numbers, or the prev or next buttons results in an ad loading on a blank background. Or just blank page if the ad fails to load. To get out of it, I have to type in a new address, or close the window. I'm not redirected to the page of the thread that I was actually trying to read. Hmm...can't get it to happen right now that I've signed in and not just viewing as a guest. Is it a thing that only guests are directed to ads when browsing through pages? Edit: Yeah that seems to be the case...As soon as I sign out, it starts happening again. Makes it really annoying to read anything as a guest.
