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

I believe, TikTok does this. Basically, the Algorithm will bury your post, if it detects a bad word, so people are censoring to trick the Algorithm.

I fully expect a return to leet speak or "double-plus ungood"-like language.

I remember there being an instance in fediverse that censored profanity, so it's not always self-censorship
