My reply to you? Be patient. I wanted to post the Michael Scott gif of him just screaming no, because I can't believe you compared waiting A DAY to waiting a week. The staff member that banned you hasn't had a chance to reply yet. It's not their fault you broke the explicitly stated rules of the server, but they had to respond and help the person you took the time to grief. You broke more than "a single block", you admitted to stealing 10 diamond blocks. That's 90 diamonds you stole, or $4,500. That being said, you can wait until they have time to respond, and I assure you, we respond as soon as we have time.
Human embodiment of Murphy’s Law, at your service!
