To put how great this server is into perspective, I challenge you to describe the worst Minecraft server you have ever played. Please don't post IP addresses or names of servers, as that may not end well.
Need an example? I once tried a vanilla rule-free server (Which I wasn't a fan of rule free servers anyway) when I discovered that the server had one rule anyway.
No dirt or cobble can be placed because it "looks ugly".
Lets see...That rules out:
Repairing ugly creeper holes (Irony)
Making bridges while mining.
Farming grass or mycelium...
and the list goes on.
