Restaurants and pubs across Cornwall are complaining about a series of negative reviews on TripAdvisor left by an anonymous reviewer. These reviews criticise the food and drink of the establishments and make unwelcome observations about the staff. Unpleasant and anonymous social media posts have become an undesirable reality of today’s social media world. Derogatory internet reviews can damage personal and business reputations and cause loss of customers and profits. But is there anything that the restaurateurs and publicans can do about negative online reviews?
