hmm... well, they have the AJAX quick reply stuff there, and if I do that, I see a couple ads (the horizontal at the top, and vertical on the right). But if I just load a page, I don't see them
Even if I tell ABP to "disable" on the site, I still get blocked content. What are these element hiding rules you're talking about? I have element-collapse turned on (although I've tried with it turned off) and still I get blocked ads.
I'm completely at a loss here.
