I found this gem in the comments to that post:

I think "no" lists are most useful for naming things you don't want to receive that might otherwise seem to be in the spirit of your request.

For (a non-kinky) example, I have a really hard time reading fic where characters express their affection for each other using the phrase "I love you." In the past, I've requested canons where characters do have strong, intimate feelings for each other, and it seemed reasonable to expect that a writer might choose to have characters use that phrase if I didn't mention not wanting it. So I added the following line to my request letter: I enjoy characters expressing tenderness toward each other, but I would strongly prefer not to read them using the phrase "I love you" to do so.

And there, in a nutshell, you see the Platonic ideal of applied Yuletide batshittery of the highest order.
