(nice). They allow AI, to be fair, but there are only (9) posts that have tags for both "Jynx" and "ai_generated", so it still comes out on top for number. That is (360) vs (343), I mean. Also, there's plenty of art for Jynx that isn't on any of the three sites. I've personally been on and off looking for it myself, and came to that conclusion awhile ago. For some reason Jynx just isn't as popular as some waifumons, but it's also really spotty in terms of how the art is collected.
All that is to say: There is porn of Jynx. It's just not a lot and you have to know where to look. But I assume OP means "practically zero" as in (360) is a drop in the bucket compared to Gardevoir's (r34xxx:30k), (paheal:18k), or (e621: 20k) values. Which is sensible. I don't deny that it deserves more love, I just don't think it's reasonable to assume it will ever get the same levels. Heartbreaking, but realistic.
