Think bigger: Total Disappearance. And as a quick example of the reach, imagine if Good Member A were to quote Troll Member T from Good Member B's troll list. If so configured, Good Member A could see that his post AND ITS TIMESTAMP were ignored by another member. And, if Good Member A chose to do so, they could could investigate further, but only as far as their and other's privileges would allow. I could go on and on, but I think you get the basic picture. It could be very powerful, very simple, and very configurable.
