    ]

It seems that the post does not mention anything related to maintenance report feedback for a public flat house. The word "omgtiansupporter" does not provide any contextual clues to suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since the post does not belong to any of the categories mentioned in the question. The "explanation" field is left blank since there is no additional information to provide.
