I take it to mean that the poster is someone who is only seeking attention or trying to start some sort of commotion. I've also read it used to refer to a man or non Cafemom member posting questions to see what riot they can start among the mothers.
In public groups, it is someone who doesn't belong and is only there to gather potentially embarrassing/hurtful information to later post in their own group to, again, start a commotion. Like a "breastfeeding nazi" in a formula feeder group.
