What happens when a member posts a negative or inflammatory comment in your online community? Having negative comments, or "detractors," in your community is not a bad thing; in fact it's a great opportunity for an organization to demonstrate transparency and a culture of openness.
There's a saying: "The conversation is happening whether you're listening or not." If a member voices a concern related to the profession/industry, or even about the organization itself, the odds are that other members have similar thoughts. It's best to address concerns head-on and open up a dialogue about the issue. Although after looking at the moderation analytics from over 400 organizations representing over 100,000 communities, it actually appears to be a fairly infrequent scenario.
