First of all, sorry for the delay.
As @Paczki already pointed out, you should have a look at How to create a ban dispute .
To make it short: Please give us a reason why you think the ban was not justified or why we should unban you and put a bit of effort in the dispute.
PS: Not trying to be rude, just an advice.
Your ban: https://bans.tallcraft.com/#/player/FastAP2004
You have griefed multiple buildings and also clamed another player’s area.
Two examples of what you’ve griefed include a sugarcane farm and some things next to it.
And a player’s base/hallway with armor stands.
