It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The term "board ship" is not a common term used in the context of public housing or maintenance issues, and it does not provide any specific information or context that would suggest otherwise. Therefore, the answer is "no" for both "relatedness" and "type".
