Something like that happened to me, my 10+ year account and everything I've ever written just vanishing one morning. Even posts to a subreddit I moderate were repeatedly removed after every approval.

No idea why, (the "wrong" public Wi-fi?) but my appeal was granted and nothing was fixed.

Now I can't contact anyone, and the appeals page falsely claims that my account is in good standing and refuses to operate.

When I went looking for help from a throwaway account that I made many years ago for resume reviews, the exact same thing happened.

So at this point, I only lurk occasionally, because I'm not going to go through that social hell again, and it sounds like moderation failures have only gotten worse in the years since.
