I really don't know what to say. Your current nightmare is one I might be experiencing soon given the recent hard block Amazon Requester placed on me out of nowhere.
With the economy what it is, I know that many of us have been reduced to working for a quarter or a third of minimum wage. These random blockings and suspensions are kicks in the gut of people already down. Do they realize they might be taking away one of the few remaining source of income for some workers? We are not asking for pity, just basic fairness. If you are going to take away someone's right to work, you should tell them why and give them opportunity to defend that right.
I don't know if it will help but maybe if you contact other requesters who liked your work and asked them to contact Amazon on your behalf, that might help.
Many of these recent blocks came from requesters with no or little bad history so workers had no reason to avoid them.
Good luck to you. link
