In my opinion, it's just too complicated to be a hoax. And if newmy51 wanted to collect money, he would've asked for them instead of waiting for a 50000 petition to be completed (it can take a year or more to complete it, usually money-pickers don't wait this long).
If you still have doubts, you can mail Mr. Arem on
[email protected] and ask him to confirm it. The email is genuine, as proven by Mr. Arem's profiles:

Besides, the email belongs to Keith Arem's company,
PCB productions, so the possibility of it being fake can be completely ruled out.
