Nobody is being payed to help some random fool. If he wants them to assist him sign up for a masters at a major university and plenty of people will help him because they are then being payed to be helpful. It's not that they are trying to cover something up they just don't feel like wasting time when they get zero benefit from it.

PS: Call up a research assistant and say I will pay you 200$ an hour to help me, and they will fall all over themselves to help you out. Although buying the computer time to actually run some of these simulations would get real expensive really quick.
