This whole situation highlights another problem, you should never base a business around a third party API or service. Remember when Twitter changed their guidelines and API usage rules basically destroying companies that had built a product based around Twitter only for it to be deemed in violation of the new rules? This situation should be a warning to others thinking of putting their eggs in one basket, because if the service you've come to rely on has the final say in the end for how your product should function and if that understanding is based on loose interpretation of company rules, you are at the mercy of that reviewer.
I hope AppGratis sorts this all out, it's a heartbreaking story. I know from experience what it's like to spend months working on something only for it to be rejected.
