In this context, you cannot rule out the possibility of your competitors stoking the bad press about you. Online reputation management is necessary to nip the problem in the bud. You have every right to respond to comments that are inaccurate and designed to fabricate negative notions about your brand. Reputation management services allow you to do that. Of course, online reputation management services include responding to feedback in a genuine, concerned way. If your consumers have a problem that they want you to address, they will be expecting you to respond to their complaints. You cannot ask the ethical question there and step away from the responsibility of being accountable to people who buy your products/services.
