Minecraft wiki entry for Creating_a_challenge_map, associated text: If you want to make a map to frustrate the player, make people who play the map get kicked by a player with an optional reason. For example, use, "You are banned from this server! Reason: went to illegal point." When the player dies, they are kicked out of the game for 1 minute! However, note that this is very hard to do in vanilla survival, without the /kick command being hacked.
