I would like to suggest few more commands for this plugin.
protection delown - it only allows you to remove areas that you created. This way the users with only this permission are not allowed to remove someone else's. The owner of the area should be the one that created it in the first place.
protection listown - it only lists the areas you own
protection user addown - add user to your region
protection user listown - list users from your area
protection user removeown - remove user from your area
