After talking to Torsten-AUR- who was kind enough to provide me with information (many thanks at this point) I'd like to submit my ban appeal.

Appeal:

So I talked with my brother http://battlelog.battlefield.com/bf4/de/user/Jihadboyy/

and it seems like he was the reason I was banned for linked accounts while I had nothing to do with it.

I'd like to state that I have never cheated in a multiplayer game nor will I ever do it. If he gets banned rightfully for cheating he deserved it but I had nothing to do with it in the first place.

Battlereports of both of us in one Server:

Looks like I have been banned for Linked Accounts whatever that means but after some research I was redirected to this website...

Ban Reason:

Appeal:
I think this ban is unfair since I haven't been playing Battlefield 4 for ages now and after a friend and I decided to play BF4 again I got this message after joining some servers. I have never cheated in a multilayer game before nor will I ever do it. I hope you can give me any information on why I have been banned in the first place because the ban report just stated Linked accounts and I don't even know what it's about. I also have to state that this is my only Origins account I ever had. I also have a brother with his own PC and BF4 account so we have the same IP address but I have no control over his account nor his computer.

I don't have any special performance in games as I'm an average player.
