It seems that the post does not mention anything related to maintenance report feedback for a public flat house. The post only mentions "posted photo St John Island" without any additional context or information that would suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not belong to any of the categories mentioned in the question. The "explanation" field provides a brief explanation for why the post does not relate to the given category.
