While I banned you for theft of diamond ores, I'll treat this more like a ban evasion appeal, since you confessed that this was alt account that you used after your first account got banned. As you hopefully now understand, if one of your accounts gets banned, you are not allowed to just make a new one and play again. You have to appeal your ban first.
If you wanna return to the server, please answer these questions and put effort into it (trust me, it's better to spend few more minutes with it, than waiting day or two just for me to ask you new questions because I was not happy with your answers)
1) Why do we don't allow banned players to join with new accounts?
2) Your first account got banned, why you did the exact same thing with your new account?
3) How can I know you learn from this, when you decided to evade your ban (two times)?
