Traditionally the method is there are some things that people just assume exist and for things outside that circle they require some smidgen of evidence to believe in. It is a bit like me saying I believe there are people in the Arctic (never really seen evidence of it, but seems reasonable) vs. pixies (if I'm being asked to believe in pixies, I'd like to see some evidence). The idea that there are sites promoting eating disorders does seem to me plausible by default, but nomilk does allude to a good point that without examples it is hard to talk about harms. These sites, if they exist, might be quite difficult to find without going and looking for them. I don't remember ever seeing a hint of such a site.
