It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The term "sketchy business" is not specific to any particular issue or category, and without more context, it is difficult to determine the exact nature of the post. Therefore, the answer is "relatedness": False, and the type is "none".
