Now, I just felt that OP is quite pissed because of those users asking questions redundantly/repeatedly. Although he already stated the limitations of the rewards based on activities but people doesn't get it quickly...

And foremost, I don't think quoting the whole image is a nice way to reply on that.

Anyways, as the OP have said that he will pay the users with his own money, then I can now perceive that these rewards are only meant for beta testers - well, it shouldn't be bad as for the goal of this project is to build up a community. Rewards are only like compensations. If you're ready enough I can also help you by spreading the news regards on this project.
