Since backdating would be one of the ways to fake this, the onus lies in those that claim the prediction was legit.

That's how evidence works for extraordinary claims. Alas, scientific rigor is a harsh master.

"extraordinary claims/extraordinary evidence" isn't scientific rigor, it's adding qualifiers to make the evaluation of the claim and evidence more subjective.
