It seems that the Twitter post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post simply mentions "berlin wall singapore" without any context or relevance to the topic you provided. Therefore, the answer is "False" for the "relatedness" field, and I couldn't identify any type or explanation for this post.
