Here's what happened:
I was wandering around when I saw this big old building, with iron doors, except the iron doors on the right were missing. So I go in to look around and I find this wooden counter. Behind the wooden counter there's a hole in the wool floor so I'm like "alright, i'll check this out." So I go down there and there's stuff all over the place, and a whole bunch of unlocked chests. I go through the unlocked chests and take everything of value as fast as I can, so I don't get caught by the owner, who I assumed would be coming back sometime soon, considering the base was griefed into and generally people repair that type of thing pretty fast. I don't know who griefed in originally, or who goldensword is, but it's a safe bet that whoever was there just before me was the person who griefed in.
