I've got this once before and I got this again:
As you can see, there's no 'Reject all' button that seems to be fairly common. As you can also see, the list is really, really long. As you might have guessed, I'm not going to click that many things manually. And as you might guess, this doesn't exactly make me want to not block ads here. I don't mind allowing ads from sites I want to support, and I would love to allow them here, but as you can see, there are certain... issues.
Also, that's a ridiculously long list of trackers.
