Oh, you are windows2333
So, you consider breaking 100 blocks within mason7676's house a mishap? What must have you been thinking when you read the "No griefing" rule?
First, you took down Shadowninja2121's tree at the top of the house and started blurting words at him, and arsenic_shark even warned you not to do it. You were told MULTIPLE times to stop chopping down the tree (which was there for decoration purposes). Now, I find that you took out a small room within mason's house. This is unacceptable behavior and we will have NO part in it. This is hardly a mishap.
The ban stays at 4 days. Hope you learned not to break anything within other people's properties. Your house is still intact, so don't worry about that.
