I stopped using Reddit last week when they shadowbanned me for, I assume because you cannot know for sure, saying something related to gun violence in America and my local area in a political subreddit. I only ever commented about sim-racing at any other point in that account's life, and so perhaps it was shadowbanned for posting my own YouTube videos that were not monitized and had like a dozen views? I don't know, and I don't care, my mental health has never been better than the past week!
tl;dr: I quit Reddit because I didn't want to make yet another account, and my life is better for it.
Edit: Also, I've been trying not to come into HN political and pop-culture threads too much, but am failing at that. Maybe today is the day I start just hitting the technical threads!
