It seems that the Twitter post "stycay" does not relate to a maintenance report feedback to a public flat house. The post does not mention any specific issues or facilities related to public housing, and does not appear to be a complaint or feedback about maintenance. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This is not related to public housing or maintenance issues."
