I do think Medium has its favorites, Alison. Two days back, I got an email from their Trust and Safety folks warning me about going against the Medium rules. Point was - tagging people to garner views and reads. After I got a little mad, furious, and cooled off, I could only laugh. I wrote back to them saying I had no need to do that because hello, not part of the MPP and thusly, no point. So anyway, chastized, I am now not tagging anyone because slaps hurt. Also downloading my material regularly :-).
To answer your question, no zombie drafts. But the opposite. I cannot scroll and find the older drafts.
