Minecraft wiki entry for Player_versus_Player, associated text: If you can't hurt them from the outside, hurt them from the inside! If possible, join your enemy faction while you are still able to. If you get into their base as a faction member, wait until the faction moderators are all offline. This is the best time to strike. Take their best valuables, then break the furnaces, chests, and burn the items with a flint & steel. If they have a water mine, block the water. If they have a staircase mine, put a lava or two at the top. Go to the "/f home" and dig a hole. Put lava in it, from the ceiling and make a wall so as soon as they "/f home" they will constantly respawn in lava. If you have spare lava, fill the place with it! Make sure that there aren't any hidden chests, and destroy the farms if no one in the faction catches on. If possible, if they don't know you griefed/raided them, wait until they repair their bases with more food/loot and restart the process! Remember to give loot to your actual team after each raid.
