I’m answering this with all the coldness that Quora Moderation has earned. Remember: it’s just business.
The normal appeals process is the only one that Quora wants you to use. Anyone can lodge a ticket, saying they’re appealing, and nothing’s stopping you from naming person X rather than yourself in the free text of the “I want to appeal a moderation decision” form. The form certainly doesn’t specify that it’s a decision against you that you’re appealing; you can hyperlink to someone else’s collapsed answer, for instance.
That’s the normal appeals process. It can take months for a reply (many of us can confirm as much), and if the decision is negative, you get no reply at all.
Quora used to have dedicated email addresses for appeals, which are now officially being phased out: Why does ‘moderation@Quora.com’ not work? And why does the email Quora gives, ‘appeals+other@Quora.com’ not work either? They want you going through the one channel, which is manageable.
This likely is why the informal channel, of directly emailing a moderator (or topwriters@quora as a proxy), is no longer being volunteered on Quora, though it was last year. You can still try that channel on the user’s behalf. You can, if you are a Top Writer, chat to a moderator directly on the user’s behalf. I have seen occasional reports that this still happens. It may work, it may not.
Of course it’s not in Quora’s interest to promote by-passing formal channels, and relying on the favouritism of Top Writers.
Of course having a default appeals process that takes months and acts like a Schrödinger Cat In A Box is not in Quora’s users’ interest.
The divergence between Quora’s aims and the users’ is an exercise for the reader.
