It seems that the post does not relate to a maintenance report feedback to public flat house. The term "sgracing" is not a common term related to maintenance reports or public housing, and it does not provide any context or information that would suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not related to any specific category. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
