Ban Appeal :/

Name: JamesDaGuru
Ban Reason: Griefing
Did i know the rule?: Yes
Why did i break the rule?: Because I was bored, but I didn't break any rule. There isn't a sign at spawn saying you can't cover a house in blocks.
Will i follow the rules from now?(One more ban= IPBAN): Yes I will, and I promise I will

Also, the house wasn't claimed, and there was nothing in there. Which signifies that no one lived there ...
