Even though it was your brother who did the spamming we don't tread too light on situations like these. Unbanning "just" an account I'm not even sure how that would turn out in the end and if the other ban would stay.
Either way is that we don't take responsibility if someone in your family or other friends cause chaos in the game and not you. If you use the same computer/internet as someone else that also plays FH you need to make sure they don't break the rules as well. We can't keep track on these things, neither can we run around and un ban people because of this.
Another thing to keep in mind that subjects like these should stay off the boards, if you really have to talk about this you should send PM to the mods/admins.
