My husband was banned without reason on this server by the Anti-Cheat. He fought with a hacker on KitPvP (I do not remember his exact name), but that hacker got away and instead, Kobayashi Yoshizuki was banned.

I am new to this server, so I do not know how to create an appeal after the necessary details you want. We have clearly explained what has happened. I hope it will be solved soon.
Thanks for understanding.
