How to protect your chests.

[The Black Sun]

Don't use Tnt unless you want it all gone. But other than that, good guide. You should probably put in there to cover it in smooth stone for those using an x-ray texture pack.

Cover it in iron ore or tunnel into a coal deposit, even X-ray mods show ores but most xrayers are not about to go out of the way to mine some coal or iron.

Or instead of building traps and hiding stuff you can go get a "VIP plot" in any town, then just place a dirt block on top. Since you are the only one able to build or destroy on that plot you are the only person who can access the chest. Why bother actually playing the game when you can just cheat? This is why I hate towny.
