Well, I know there are beacons, but what about the places in the main world server that are not beaconed protected. Players can flood water and lava and just ruin the beauty of the nature? how are you going to address that without preventing the freedom of the saint players.
Had a huge minecraft server, that problem addressed by preventing water and lava to be placed on air block, but couldn’t address players creating naughty monuments or just filling an area with random blocks that ruins the beauty of the generated map.
