This player is already banned by ApexCandy
But next time when you report, please have more evidence, the chat doesnt prove if the person is hacking or not so we cant ban them.
I think the problem is because you are doing /kick /ban /mute.
When you're on your playerserver you need to do /ekick /eban /emute, due to /mute /ban /kick is for cubedcraft staff.
I am pretty sure this is the problem here. if this doesn't work contact me and I'll gladly help you
