Minecraft wiki entry for Things_not_to_do, associated text: Wherever you are, make sure your base cannot be destroyed by endermen (particularly in the warped forest or the End), as they can pick up some blocks, and preferably use strong, blast-resistant materials unless it interferes with the aesthetic that you care about, so that neither creepers nor griefers can blow it up. Lava and lightning both have massive destructive power, so if you don't have a lightning rod and "Fire spreads" is on, try not to use flammable blocks like wood or wool.
