You're not the only one, many people have it, from what I have heard from the forum of fourdeltaone. As of right now, this type of ban is a hardware ban, much like a IP ban but much different though. With this ban it is permanent, unless there is a bypass which there is a couple of them, but those simple tricks won't do any good to the aCI. With this ban, you are "removed" from their services, the people who are banned are able to start the client but however they cannot fully play their own favorite servers.
So yeah, that's all I have now.
