Minecraft wiki entry for Player_versus_Player, associated text: Teleport killing- In the chat bar you see a new player and you want to take their stuff. They don't have any faction, so you tell them "Teleport to me and you can join my faction" as soon as they arrive mercilessly slaughter them. (Note that this can create a bad image for you on the server and could potentially get you banned, so only do this on servers that this is allowed or you don't value).
