Tessa, thank you so much for sharing all this. Perhaps I misunderstood your initial question -- I thought you were looking for guidance about articles that had been identified as high quality by Medium's curation team, as a way to inform your own writing. Apologies if I didn't understand what you were asking for.
Unfortunately, I don't know anything about the issues you had several years ago so I can't comment on that -- but I can assure you that at this time, there's nothing on your account that would hamper your reach or distribution. If you ever have specific questions about your account, you can reach out to my pals in user services via https://yourfriends.medium.com ❤️ We're here for ya!
