site approval policies and suspicious payment activity cover-up
Google never gives an specific reason and specific solution. Just vague reasons like suspicious behavior on payment activity and a link to policy page. Nobody calls. You cannot reach support. Even after losing businesses like affiliate programs and feedburner adword ads and others google is not improving tech and customer support. Trust me every client and every dollar that you lose is going to your competitors. Quality is a very subjective term. Only way to resolve these issues is to have constructive discussions with other parties. Google is the biggest siphoner of traffic to other sites but it does not allow similar competitors to compete. A very antitrust practice.
