Obviously nothing is helping. In fact, it got worse. On my iPhone, an ad has now entered not just on clicking on a blog post title to go to that specific post and its comments, but on Kevin Drum's blog page overall.
In case it would help figure this out, I went to the site on my laptop (Windows with Firefox), where of course we've more options when we go to the ABP red icon at top left on the browser's main bar (after URL, search space, and home icon). I clicked on "Disable on Mother Jones," where of course the drop-down menu automatically adds the name of the current page (in this case Mother Jones) to "Disable on." Then I reloaded. I hoped that I'd then see the same ad, could right click on it to bring up an option to block it, and so see what filter is required.
Alas, while I saw plenty of ads, they're different ads than on the phone. Not tacky jewelry and education, but mostly political ads. And of course they went away again when I clicked again on Disable to remove the check mark, then reloaded once more. So I don't have much further info to give you, other than that the site's version for mobile is different enough that you should be sure to try to recreate the issue only there.
