The given Twitter post does not seem to be related to a maintenance report feedback for a public flat house. The post mentions a jockey named Vlad Duric and race numbers 9 and 10, but it does not mention any issues or concerns related to maintenance or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not fit into any other category. The "explanation" field is left blank because there is no explanation for why the post is not related to maintenance report feedback.
