Only read the first page, but just cause its not real, doesn't mean its a hoax. It's probably just fanart or a poster for a fanfic or something and was never meant to be taken as real.
I wrote a Jurassic Park 4 fan script many many many years ago, and it was mistaken over and over and over again as being the real Jurassic Park 4 script. AICN reviewed it as real, many torrent sites and script sites had it up as real, and one idiot even printed it off and tried selling it on Ebay as real. Whenever I tried tot ell people it wasn't a real script, I was called all sorts of names and such. Thing is, it was never even meant to be taken as real. it was a fanfic I wrote and posted on a couple JP fansites and my own website I had made for it at the time, and a few idiots started passing it around the net as real and then I was the one that had to take the fall for it.
So just cause it's not real, doesn't automatically mean its a hoax or someone trying to start a false rumor. Its more then likely just fanart that was never meant to be looked at as anything more then that.
Now, since I only read the first page, I'm sorry if this ground was already covered.
