Dear Anon, Hi, I'm the moderator of that page. I've been very strict about spam so that it will only be used to find support on FB. However, there are other newer pages which have attempted to use the fans list to sell juice or Tshirts or lots of other things. It can happen on any public FB page. I guess a page that big is pretty irresisable to them. They use "friending" as a method of networking.
I personally know of hundreds of people who have made good friends there, creating their own smaller circles. Most members are real people but, yes, there are schemers every where. Even in here - posers trying to use patients' info.
Please feel free to email me if you have a problem. kelly @ rawarrior .com
