That's the main reason I don't play on multiplayer servers. Just create my own for my friends to play on. No shops or pre-built farms, just start out with a block of dirt, a couple saplings and bonemeal and your wits.
Modded obviously. My most recent skyblock server was using a modified version of the Agrarian Skies 2 mod pack.
I really do need to boot that back up again and have a play. Not been on it in ages now!
