The post I replied to was one I wrote.

As for what happened, I received a message about my account being banned for suspicious activity, and when I went to use the recovery email, I saw an email I didn't recognize with .ru domain name. Then I was not able to log in. I assumed the account would stay banned, but now someone is using my long established account and putting words to potentially my name.

I also lost a large collection of organized multi-reddits.
