I just successfully appealed a ban on a 6 year main with 2 prior bot busting bans. No proxy. No appeal option.
Put in an appeal like you did 9 days ago. Unbanned today. I'm assuming it was related to me playing legit (writing AHK for everything) and only actually botting for under a day making it look like my account was stolen.
So if your story is true you could have a chance at appealing.
Update to this situation:
Main account unbanned after no appeal - Assuming because the account had so much recent legit playtime and only one day of botting made it look stolen? Or perhaps that I bot from my work IP and home IP. Still waiting to see if they'll have mercy on my mule account that was also banned..
Either way - been botting on an iron account same ip same machine since this ban and just finished sitting out the first 2 day ban after suiciding agility for almost a week straight to test how quick they'd get me after my main ban. Took a full week before the ban was applied on the new account. Could have been a delayed ban.
My conclusion: Mirror mode is the way to go. Especially if you're risking a main. Though it's probably not worth it to risk a main unless you have no prior bans.
