Minecraft – Why can I move water in Minecraft SMP Alpha

Unfortunately on a server where there are no rules against griefing and everything is destroyable, there is no foolproof way to "trap" enemy players.

• Any redstone contraption can easily be avoided, as it requires stepping on a pressure plate which can be seen by anyone looking for them.

• Traps in pitch black can easily be avoided by small investments in torches by an opposing player.

• Any wall can be tunneled through.

• Aside from triggering redstone traps, the environment won't "update" in response to a player, thus any crafty player can avoid all traps with a little resources.

The best way to keep your stuff secure is to hide it. The best way to do this is to use a servers /home and /sethome commands. Simply go deep into the wilderness. Dig deep into the ground and ideally try to find a naturally occurring lava source. Replace the blocks above you and put your chest inside the lava source and /sethome. Even players using x-ray tools will only see the natural lava source (torches are a dead giveaway of a base) and won't be able to see the chest.

TL;DR: Bases can not be secure, and hiding is difficult from x-raying players. Put a chest in lava and walk away.

Zombie Pigmen tend to travel in groups. That's why they are so hard to kill.
