What server? And why did you grief? Why would you want to destroy someone elses hard work?
Deviantevil
I did destroy like.. 2 blocks on like 2 houses or something, to get in and check them out.
To take the whole story,
I had not been on Deviantevil for a few weeks(about 2 weeks because of school) but some days ago, I got on and the guy who "owned" the town I lived in told me that the town got disbanded because of inactivity and such, so I grabbed the last of my stuff and went away to find somewhere else to live, came to this "ex-outpost" for that town with a few houses in it, some were open and some were "locked", so to get into those locked houses, I did destroy like 2 blocks just to get in and well, as I said, check it out and check some chests, because it is allowed to steal from others.
But I've learned something, don't grief. So yeah, it wont happen again, I promise.
EDIT: Yes, I've read the rules and I do understand how you do things here.
