That's not the point. The point is Heart of wood will still be removed despite your protests. Hence, it was unsuccessful. The most you can say is that you got Turbine's attention. Forum flaming would have been sufficient for that. Hence, standing around on a bridge did not accomplish your goal which was to "stop the heart of wood trade from being changed."
I don't see any difference in the player base still playing after excluding you protesters. You don'r represent the player base.
