This is what I saw too. Particularly this paragraph: We confirm that your app has options to report and block abusive users but your app does not contain functionality to report objectionable content. It may be worth explicitly pointing out to them that the "Report" button in the screenshot reports the comment, not the user (even though it is in the same menu as the Block User button). You may even consider changing the text on the button to "Report Comment" as even to me what is being reported isn't super obvious. With all of that said, it is a serious that the reviewers are so reluctant to provide information on the problem. Even separating the custom message from the template, rather than sandwiching it between 4 paragraphs of copy-paste, would likely make it easier to understand their complaints.
