> valuable posts on Reddit from years past are easily retrievable.

Rant: Several years ago, everything I'd ever written for over a decade on Reddit vanished one morning for no discernible reason, including all nested replies from other people. I appealed, my appeal was "granted", and nothing changed, except the appeals page refused to work because it said my account was already in good standing.

I dug up an ancient account I had used for resume feedback, asked around in the help subreddits, and it too was killed the same way.
