Well there's two types of ED communities. There's the healthy ones that try to bring people back to good health, such as http://www.something-fishy.org/
and there's the bad type such as livejournal (I deliberately won't link to it) that promote, essentially, death.
As sites like something fishy wouldn't promote anything that's triggering, I presume you mean you saw it on the bad sites. I guess that's sad, as people like that will worship her and look to her for "thinspiration".
I hope one day Olivia is able to come on here and give us her thoughts on all this.
