It seems that the tweet "drop rainbow centre singapore" is not related to a maintenance report feedback for a public flat house. The term "rainbow centre" is not a common term used in public housing contexts, and it is not clear what specific issue the user is referring to. Therefore, I have marked the relatedness as "false" and the type as "none" with a brief explanation.
