Christina I agree. The negatives on socail media are incredibly valuable and should be to feed directly into customer relations and marketing strategy. We often tell companies that whether they monitor them or not, conversations about their brand are taking place on socail channels so best to be involved. But coming back to your original point, if a brand is working with a blogger to facilitate their trip it is only fair that if something negative happens they have the opportunity to defend themselves. If the brand didn't facilitate your trip then there are no issues but relationships need to have dialogue and trust if they are going to be sustained.
