I also believe that the flux of correct information also allows these wanarexics to "talk" symptoms that they don't actually have. The wondrous psychological fraternity are calling these types, cyberchondriacs. We all are aware (even if loosely) what a hypochondriac is. Just add the internet and we have a cyberchondriac. For a cyberchondriac this access to information is gold. There is so much at their fingertips, and with seemingly consummate ease they can troll into a genuine sufferers diary and "lift" their feelings from the screen - and make them their own. They can then infuse these symptoms into their psyches, leading to incorrect diagnosis by their GPs, due to the convincing nature of their words.
I am not knocking any communities, but just had a thought as to the rise of Hyper-wanabes, and in my opinion this has something to do with it.
I am not saying that the communities should stop providing this information. It's sorely needed amongst all the other crap that is posted around ED communities. A light at the end of a very tedious tunnel to be honest. There is always a danger in providing information. Some know how to use it correctly and others feed on it to create symptoms that don't exist. Worse still, use the information, incorrectly comprehended, and offer it as advice to their community members. I could name a user, but I am aware that those that "know" me, will totally understand who it be that I am referring to.
Anyway. Just a thought.
