You seem to be a little lost on what to do here, so I'll explain a few things. Please read this first so you can understand how to write an appeal (
http://minerealm.com/community/viewtopic.php?f=20&t=678). Next, read this thread please so you can understand the official rules of this server (
http://minerealm.com/community/viewtopi ... =20&t=4200). And for good measure read some other ban appeals here so you can understand the process better (
http://minerealm.com/community/viewforum.php?f=20). After you've done all of that, ask staff what you have been banned for. When they tell you that, you can then make a statement of apology and why you should be allowed back into MineRealm.
One last thing, do not lie to staff about what you did. They have admin tools that keep track of blocks, chests, and basically everything so lying is just going to make it much worse. With all of that being said, good luck with your ban appeal and I hope to see you in MineRealm.
