I don't get it :(

There's a no griefing rule and a stealing-is-allowed in the wilderness rule, but I asked in game and someone said getting over nomads walls was allowed? While I was wandering to the spot I claimed I saw several random small huts with walls around them and it just confused me why people would make walls if other people could just build to get over them... Can someone clarify what the rule is on completely enclosed nomad vaults? Like a chest in a house with no doors or openings. Or do you have to leave your chests completely accessible like on other servers?

I beleive you have to hide your stuff quite well. And as for the walls, well, whenever i build walls as a nomad i do it because it keeps mobs away from the front door( sssssSSSS) and it looks quite good.
