A little suggestion.

First off I would like to say how much I love this server and specifically skyblocks. I thought it would be a cool idea to add a pvp area or be able to add a pvp area to your island. Maybe there could be a way to challenge a person to a pvp battle and if they accept then you can fight them so that people will not kill other people when they teleport to someone. It could also disable commands and the person who dies will still lose their items but since they challenged them, it will not be a problem. After someone dies they will no longer be able to fight that person and nether will the victor. Adding this allows people who have nothing left to do work on getting op stuff to fight other people. This could also be really fun between friends.
Please tell me what you think of this idea. I really love this server and i just want to help make it better.
Thanks for reading!
