Lemmy has hard coded censorship. It can be disabled via the code, but irrc not via config. It was a large source of criticism, even 3 years ago: https://linuxreviews.org/Lemmy
Wait, words are censored on Lemmy.ml!? What the titting fuck?? If I want to read "naughty words", that's my right as a grown-ass twat! These bitches have now pissed me right off...
