Hiya,
So this is the reason you’re banned at the moment: https://players.tallcraft.com/player/663b10ab-b1e6-44fa-9086-b072c889f22e
I banned you since you did break a load of diamond blocks in Metype’s mall, which is clearly against the rules. However, since you seem sincere, I think the ban can be reduced and I’ll lift it in a week. In the meantime, I recommend you get acquainted with the rules of the server here: Minecraft Server Rules
