I think I'm starting to crack the code of Jezebel posting, so I'll present my hypothesis in hope to ease the pain of my fellow sufferers. Now I'd like to begin with the distinction between women that are Jezebel's or pretend to be one of them and those who are just simply beautiful or hot. The latter group of women, more precisely photos of them, appeal to the "natural" beauty of feminine essence. Pictures of them mostly show normie women with great bodies standing in poses that look like they are taken from established catalog of model training. Those picture mostly appeal those who find nice curves, big tits and fat asses exciting.
Now, the Jezebel posting is something a little bit more distinct. As you can see from the op's image, the appeal of it lies not in the model-like appearance of the female and not in the ripe curves of her "natural" body. Those are absolutely absent. What it tries to make explicit and where its effect is grounded, is in the certain structure of fantasmatic elements. Cat ears, her pose, milk being poured on her tongue depicts well known Neko fetish that comes from Japan and has its own category in anime. Jezebel posting combines elements of "real" women (3D) with imaginary images (2D). In this way it creates surplus enjoyment (you not only enjoy the beauty of the female but also the fantasy elements).
This explains why 4chan posters are so frustrated by Jezebels. We know from experience that enjoying 2D anime girls can be viewed as compromise to feeling attraction towards real life girls (I can't have any contact with real life girls, so I'll choose anime girl which will be at my will). What Jezebel posting does is that it mixes the sacred (fantasmatic imago of certain fetishes) with profane (3D women). You then see beautiful women appropriating fantasmatic anime culture and second object choice of those who had to make a compromise.
