It seems that the Twitter post "crab man singapore" does not relate to a maintenance report feedback to a public flat house. It is not clear what the post is referring to, and it does not contain any information that would suggest it is related to public housing or maintenance reports. Therefore, the answer is that the post does not relate to this category.
