Minecraft wiki entry for Player_versus_Player, associated text: Generally, the group may know each-other personally. If three friends chose to do this, and each friend tells two of their friends, then we already have nine people ready to attack. Doing this makes it easier to create order and hierarchy. This is also done to deter any traitors or turncoats in the group. Some of these groups go into faction servers, claim land, and make a legitimate faction. They will probably use the faction as a temporary "bank" for what they steal and make. They will build a secondary base, and will use this when they attack. They are highly armed, and are equipped with heavy enchants, potions, lava buckets, redstone, TNT, and whatever the Modifications on the server make available. They disband the faction, and move to the other base and create a new faction, (if they make one at all) and begin their attack, or they may each stay factionless (to avoid detection) and cause great destruction to large bases using the exploits above, communicating attacks via a third-party social platform.
