Does anyone know what happened to the Aliensandufos subreddit?

I used to post on it and it had around 70k members, but it disappeared a few weeks ago. Did someone not like what was being said there. I find it hard to believe a larger subreddit would shut down even if it’s kind of unnecessary with the larger separate Aliens and UFOs subreddits. I really liked that it had a pretty good community without gatekeeping like the larger subreddits.
