I've played with autumn a lot in game and never suspected it was an alt of someone banned. No issues there so far.
Malicious ban evasion is truly meant to be a permanent ban but the fact that you are posting here, prior to your alt being banned, tells me this isn't malicious.
In fact, I didn't know autumn was an alt until this post.

Only advice is it's probably best to stay off the server as autumn until this umban request processes.
