Why is Randomness so Hard to Prove?

The original poster claimed that QM could be used to disprove determinism.

QM is not inconsistent with determinism and could never be used to disprove determinism. To see why this is true, imagine a deterministic simulation of a QM universe

[unless you make non-determinism an assumption of QM but its not a neccesary assumption]

I think you've alluded to a computer simulation of the universe before and here you put it forward as a possible (ie in principle) approach to show the QM is not inconsistent with determinism. BUT, this assumes it is possible, in principle, to carry out such a computer simulation wheras QM says this is not possible (as QM is understood at present, ie no hidden variable theory)

I don't think thats right. I'm assuming by hidden variable you mean that each particle contains within it the information that will decide its measured spin. This is not the case in the computer simulation.
The simulation does not contradict Bell's inequalities if that what you mean.
