Moderators are players who are respectful, and play the game by the rules. If a player who has a silver "M" shown next to the player's username in the lobby, that player is a moderator. Moderators can ban and warn players by typing in /ban or /warn in the lobby. Sometimes, when the intro of the game is done, a message will have shown up saying a member has became a moderator. This message will not show up if you are disrespectful and always breaks the rules. Moderator's can ban hackers eternally.
