To defeat the troll we must understand the troll. Lesson one: never feed a troll.
Great article from a former Internet troll. Most Community Managers will already know this from painful first hand experience, but it’s worth remembering this in the heat of a trolling:
You will never beat a troll. You will never change a troll’s mind. You may delude yourself into thinking that you proved them wrong, however, never in my years of dealing with trolls have I seen a troll lay down his or her arms and say, “You know what, you’re right. I was so wrong.”
