add more restrictions/limits to incoming players.
1) In order to cut down on the trolling, spamming, and other possible forms of breaking rules please require an email to register. While anyone can just create a fake email this will cut the number of people making accounts to troll or spam. This will also make players accountable for their actions should they choose to break the rules as currently they can just make another account.
2a) Require completion of the tutorial and the Draco missions before using the chat. This will simply cut down on people asking questions about how to play before they've even done the quests. These quests only last a few minutes of gameplay and if they have any questions afterwards they can ask then.
2b)This may also require that the Draco missions explain that grass is not ground 0 and players must walk out of Origin in order to find empty ground. This is a common confusion with the Draco missions.
2c) Maybe you could create a separate tutorial area with permanently empty ground, possibly blocks placed here are removed after five minutes so incoming players have empty ground right near the mission to work with.
Overall I think this suggestions will cut down on inappropriate behavior as well as pointing players in the right direction when first joining the game.
