It seems that the post does not relate to a maintenance report feedback to public flat house. The word "de sea" 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" because there is no specific type of information or topic associated with the post. The "explanation" field is empty because there is no additional information to provide.
