It seems that the Twitter post "blue purple singapore" does not relate to a maintenance report feedback to public flat house. The term "public flat house" is not mentioned in the post, and there is no indication of any issue or inconvenience related to housing or facilities. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since the post does not fit into any of the categories provided. The "explanation" field is left blank since there is no further information to provide.
