That sub is one of those truly depraved corners of the internet I wish I'd never seen. Most redditors are just lazy smelly fat pieces of shit with no ambitions or measurable skills: shitty people, but most can be made some use of. "dying to be fat" just takes it up even past regular fetishism into seriously not mind safe material. It's not terribly far off from kiddy porn territory in terms of truly disgusting and dangerous depravity IMO.
