Self-censoring is just getting stupid nowadays. I can't remember which social media platform it is, but you have people censoring words like k*ll, and I just find it utterly ridiculous.
tiktok and instagram shadowban any content that mentions or writes kill, death, suicide, assault, sex, rape, nazi, among others. Apparently, YT will demonetize any video that uses those no-no words, too
Tiktok has some super arbitrary automatic filters that look at description + ORC text in the video and will black hole anything that matches certain words.
Like anything, there ends up being folklore about what words trigger the filtering (cos there is no public list) so people end up censoring stuff that might actually be fine, but it's hard to know for sure
