I have a similarly buggy experience: My 13-year old account with zero history of problems (and incidentally 500k comment karma) was randomly shadowbanned. I used their appeal page, got a message apologizing and saying my appeal was granted...

... But it's still shadowbanned and everything I ever wrote over those years is still gone, except now the appeals page doesn't even work because it claims my account is in good standing.

So I went looking for some kind of human help or support, but another old Reddit account (a resurrected job search throwaway from 5+ years ago) got immediately killed the exact same way, the lying "granted" appeal and all!

It certainly revitalized my interest in using personal-blogging for information instead of contributing anything to Reddit's decaying ecosystem.
