By all credible reports, yes, not only a hoax, but attempted fraud. See post #9 for more details and links.
what about the frank baker case/documentary on the science channel? (and similar cases) was that a hoax too?
People attempting to defraud others usually do appear sincere.
however watching the documentary he seems sincere.
Notice that every attempt by Baker to set use a crowdfunding site to actually get money from people has quickly been taken down. These sites bear some legal responsibility not to facilitate fraud, which is criminal. Social media sites like FaceBook, which don’t actually handle money, have less legal responsibility, so tend not to take down pages like Baker’s.
he also set up a facebook page about raising money to fund a cure for his condition.
