I don't tune to 200 for the sole reason I cant keep up with that high of an amount of stupid in the world, and if they Pm me, I indulge them with such an onslaught of information that they soon realize that they have no way of winning a battle of chat as well.
Don't let it bother you, stay true to being a nice guy and let the fools be fools..
