Oh, gotcha, my bad, I misread it.
I don't have any coding knowledge, so I'm a bit useless here sorry.
Wouldn't it be possible to just add the site like?
Lemme.ee##div.post-listing:has(span:has-text("/motherjones.com/i"))
I'm assuming the code ignores hyperlinks and just looks at the code to find a certain string?
Well, hey, at least you know how to do that now!
