I read Invisible Monsters by Chuck Palahniuk some time ago. It's so messy. It had the sort of horror that you could find resonated in everyday life, wherein someone's life is ruined by circumstances, and the problems they faced were very personal, mental disorder, trauma, addiction, etc. The characters were deeply flawed, and the plot twist really made me put the book down just to absorb it. It didn't have an ending I'd consider happy, more resolute than anything else.
I usually stay in my fantasy/sci-fi bubble, and it was so far removed from anything I had ever read before.
I wouldn't say it's unaffected. The quality of the content has dropped, less people are posting which makes the feeds look and feel stagnant, and some subs are just gone now. Whether or not that stays the same months or years from now, who can say?
I don't think any censorship is happening though. Reddit is still very much an internet subculture thing and fediverse apps even more niche.
