This is the first I've heard about "nectar pores" on neps, especially showing up as frightening black dots on the leaves. I haven't personally seen these on my plants, but I'm hoping someone more versed can chime in, because this would be worrying to me if I saw them on my own plants. One would think if it were a natural product of the plant it would be either uniform or symmetrical in nature, rather than scattered randomly over the leaf surface. :/
They are nectar glands. Nepenthes glandulifera is particularly pronounced in nectar gland expression. I suspect they developed on the leaves as a sort of side effect from the same specialized glands in and around the traps. If you look closely you can see the same glands on the traps and tendril of this glandulifera specimen: https://www.flickr.com/photos/99611974@N05/22516098647/in/dateposted-public/.
