It seems that the post does not contain any information related to a maintenance report feedback for a public flat house in Singapore. The post only mentions "posted photo east coast singapore" without providing any context or details related to maintenance or housing. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
