For those who've been lucky enough to miss out on it, LJ has a number of communities that are "Pro-mia" or "pro-ana". Mia and ana standing for bulemia and anorexia. these communities advocate bulimia and anorexia, or at least emulating the behaviours thereof, as a healthy lifestyle, and a good way to look thin. Yes, there are people so thoroughly nuts. These folks also cause trouble by picking fights with communities for large women, or healthy weight loss.
Well, some guy has made a parody community: pro_gout
For those who lucky enough to have gout!
