Fetishes like inflation or vore have to ignore the realistic consequences
Inflation and vore are what I'd classify as the
absurd fixations type of fetish. Yes, you can inflate a balloon and snakes swallow their prey whole, but these specific types of situations cannot be replicated by human women without expensive props. None of the people who are into either type of expansion would ever care about realistic consequences because they recognize that their fetish is an impossibility that can only be satisfied via artwork. This is why no one is going to complain about that BigBig guy you posted earlier not drawing his girls suffering sever spinal injuries from having multiple 130+lb people packed into their guts.
Chunky girls do exist though and, aside from the typical lunacy you see on the internet, that basis in reality makes me hesitant to call BBW a fetish instead of a preference or at least not to the same degree as the absurd fixations are. Someone like BWS drawing girls well over two tons and suffering no consequences are the same deal as anime gag boobs: arousing for the person whose into them, but also recognized by the target audience and illustrator as completely impractical. Some retards do try to make absurd sizes happen in real life, whether it be the FA, the fat girl herself, or both working together, but those are the fringe outliers who unironically enjoy Saxxon's cloud landscapes and forgot what the second B stands for.
I speculate that the literal deathfat fetish embodied by PDC is an extension of these fringe retards, possibly in the same manner that
@Cuntspiracy Man pointed out with the wonderbread guy's spitefulness slowly warping into a fixation over time. I can't quite pin down the source of the cruelty aspect though, and let's not fail to call a spade a spade these fuckers are getting off to misery of the depicted women and nothing else. Off the top of my head it could just be that these freaks are people who watched my 600lb life as middle schoolers and their malformed zoomer brains ran with the idea.
Bws also makes genuinely well made art that doesn’t focus around literal corpses and can draw on model.
Being able to draw very well goes a long way to giving unusual interests a pass, and it helps that Salt is considered an all around mellow guy despite his considerable popularity within the fatty art sphere. PDC is only barely more competent than chris himself and thus comparing them is admittedly unfair, but if he's going to flaunt his scribbles like he's a big deal then he deserves the humiliation via revenue comparison. A similar situation exists with FFA#5, whose going to spend the rest of her internet career eating crow.
Anime girls shapeshifted into fruits, but remaining their faces, hair, hair accessories and sometimes their skin (WTF?)
You can blame horsefucker artist RidiculousCake/Ask Diamond Tiara for that shit, he's solely responsible for inventing the food transformation fetish to the best of my reckoning, or at the very least proliferating it. This is a true and honest absurd fixation if there ever was one.
