My friend and I own an Attack of the B-team server and we want to make it public. Since it's an Attack of the B-team server, we can't install any plugins.
We've spent a fair amount of time building our house and we don't want it to be raided when we make it public. We thought of building a bedrock wall surrounding it, but that would obviously take a very long time.
How can we quickly do this? Or better yet, how can we protect our house from raiding when we make it public, without using any plugins?
