I'm curious in general as to how you handle negative comments/reviews on your page. Do you keep and respond, hide, delete, other? Also, how do you handle negative comments that are on other pages (such as media pages)? I understand you cannot hide the comment since you do not own the page. Often a response there is unwelcomed. Reporting may not work, if it's not technically wrong (i.e. "[Your brand] is horrible!"). What else can be done?
