OK, I'm bothered enough to post screenshots now.

BTW, this same ad loads nigh immediately on my computer (even if it's rendering multiple times per page). It also only appears in the UA forum on my computer.

I see this ad in Every. Single. Forum. on mobile devices. In fact, I'm not sure I'm seeing any other ads in mobile at the moment. It's making the site unusable on mobile, essentially.

Without further ado…
