Hey Lokoshin,
we aren't really big, well depends what you mean by big, but most of the time the servers aren't overly full and you still get to know everyone who's active.
I tend to make large bases that go upwards/downwards to avoid loading too many chunks.
I wouldn't recommended that, distributing everything across multiple chunks is way better on the server!
Regarding chunkloading, it's totally allowed in general nothing is banned. You can read more about that kinda stuff by clicking FAQ or server history below this post.
Anyways I went ahead and whitelisted you, welcome to Stonebound and have fun on the server 😉
