Im not on this world, but I HAVE to disagree with the method used here.
What about the players who want to carry on playing? The ones who are leaving can vote to close and it will never matter to them ever again, they can go and leave. But the ones who want to stay on will lose out because they'll be outvoted and can do nothing about it.
If even just 1 player wants to continue playing then the world simply should not be closed. Its as simple as that.
