Are you sure? Because that's an old report, from february. You were recently banned by Sentinel, the anti cheat.
Anyways, I can see you have appealed, and it was denied so that's not the solution.
If you are certain that you weren't hacking neither this month nor in February then gather as much evidence as possible, and describe very detailed the situation and the last thing that happened on cubecraft before you were banned to @CrazymanJR without spamming him.
But if you want a faster response then contact him on Discord.
And remember, be patient!
If you have any further questions or need help then feel free to PM me!
