A few years ago, I once had a rat in my friend's server (strictly PvE) who would go to player homes, take all their iron and diamond, and destroy them out of spite. I didn't have admin access at the time, so I used x-ray cheats to quickly replenish what we had lost. Unfortunately it's really hard to see depth when in x-ray, so I ended up losing all of my newfound loot after falling in a random trench. Upset and defeated, I decided that cheats weren't worth it and haven't used them since.
