The only way you will fix the DF is to change how the NA player-base approaches their communal responsibilities.

Right now, if content is an empty room, when people use the DF, they walk into said room, defecate all over the floor, and then we all wonder why nobody wants to eat, sleep, or live there anymore.

You need to make people care about their actions. In the end, it boils down to accountability. And, while emphasizing individual accountability, you also need to make sure people understand they sink or swim together.

Using a grading system is fine but the implementation in this thread is horrific. It doesn't incentivize people to work as a community and only further pushes people into their rugged individualism.
