As i noticed that my server is full of herobrine threatening words and fake usercache,the plugin i want to develop is to spy all the events from the player and show all the place of command block.Somebody loves using command_block to make fake chat of herobrine.Also,the tool also can detect vanishing player and anti-cheat to the players.Once the player use cheat,ban the player and make a notification to the console.The tools also can detect the ip of the players and is able to ban the vanishing players.
