Update 1.3 With this new update, it is now possible to allow people with certain names to join your server. This is because of a new part in the config.yml called "allowed-players". This is a list of CASE SENSITIVE usernames that will be allowed. This allows people to be banned that have dream in their name, but allows the real dream to join the server. Enjoy!
Update 1.2 For update 1.2 I've added something simple but very useful. If you have chosen for stans to be frozen, then they will be teleported on an invisible, unkillable shulker below the world so they cannot see your builds! The shulker is also 16 million blocks from spawn.
Update 1.1 In the config.yml you can now change if you want a stan to be frozen before they are banned. If this is set to true, then any new players identified as stans will be frozen (with the cool powdered snow freeze effect), preventing them from moving and chatting. It will alert then anyone with the permission "stan.admin". Then they can type /stan ban to ban all frozen stans!
