Seeing as how I can't seem to find the screenshots I took of where you griefed, I'm going to let you off the hook. However, this is your last chance. You have been banned four times. All for grief. Since you are 10, I'm going to assume that you are old enough to read and follow rules. I would make an exception for maybe a seven year old for their age. 10 is plenty old enough, though. If I find any more grief--and that means ANY--done by you, I will ban you permanently with no chance for an appeal.
I will leave your ban at a week to give you time to read and review our rules. Do not let this happen again.
