It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "sea horse" does not have any relevance to public housing or maintenance issues, and it is unlikely that the user is referring to a specific block number or street. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because it is not possible to determine the type of issue being referred to. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
