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 "groundkings" is not a term commonly used in Singaporean context, and it is unlikely that it refers to a maintenance issue or feedback related to public housing. Therefore, the answer is "relatedness": False, and the type is "none".
