 The reports section shows a list of reports, originating from your local users, or remote instances (shown anonymously as just the name of the instance, without specific username).
 
 Clicking a report shows if it was resolved (with the reasoning if available), more information, and a list of reported toots if selected by the reporting user. You can also use this view to mark a report as resolved, and fill in a comment. Whatever comment you enter here will be visible to the user that created the report, if that user is from your instance.

 Clicking on the username of the reported account opens that account in the 'Accounts' view, allowing you to perform moderation actions on it.
