There's an abuse report in addition to the open letter, and a lot of very specific against TOS incidents within the community linked. It states it's for support, but apparently their interpretation of support isn't what one would hope for. The reason for the open letter is because the community has been pointed out by LJ abuse report before, and reviewed then ignored. LJ retains the right to suspend journals for activities that aren't specifically illegal, they've said as much on the other post Mel had linked. They claim they will ban communities or individuals for promoting harmful behavior. People with anorexia and bulemia could use some serious help and shouldn't be lost and alone, but this isn't what they need either. I dunno. There's probably better ways to go about it. I don't want everything shut down, but it bothers me that stuff like that exists. I was clicking around on Dirk's lj interests one day, eating being one of them, and what came up was pretty scary. Spreading attention seemed like a good thing because I wouldn't have been aware all that existed otherwise.
Anyways, I'm really groggy and wheezing and coughing inexplicably this morning. I'm not sure I can give any more intelligent response right now.
