We need some answers first and set the details straight before anything could be tossed in the middle..

How will Boonex prevent an abuse of the "refund" option?
When a product will be tagged as "to be refunded" and by whom? On what grounds? What will be considered as a "proof"? Will the admin/moderators have the technical abilities to get to the right conclusion?

When will a product may be suspended? Before, While or After the dispute investigation?

If we don't see more have every point clearly stated this thing will not work.
