That type of troll does not actually need to have a group with them. It can be one person with multiple screen names. Saw a poster here recently respond praising their own post as if someone else had said it. This person outed his own self. I never did see them on that thread again.
Hmmmm ..?? How can you tell if a person has multiple screen names ..??
And .. the Trolls I was writing about actually happened here at FR. When I discovered what they were doing, I quietly notified those posters that I knew (via private mail), telling them what was going on.
Eventually, most people knew about the game and we basically put them out of business .. it was great!!
