It's a good question and probably the hardest one we can prove, especially when it's Bitcoin related. We've been mulling the idea of adding Stripe for Credit Card payments so that you have the peace of mind of doing chargebacks if you feel you're not getting what you deserve but that sort of goes against the idea of making this a Bitcoin site. It would also incur fees we'd have to be paying just to get the money back into Bitcoin to give it away so it means less for the people.
