don't quote me on this, but anything that is part of your house is protected and is unable to be griefed. if it can be destroyed, it's probably not part of your house. And some guarded areas, like my house, doesn't always go to directly to bedrock. As for CammanduhCool refusing to leave your house and the vip, block off your warp so no one but you can access it to prevent issues and since you told Cam to leave, even in a not so nice way, he is breaking rule 9.
