On Lemmy, there's no good reason. But they may be carrying over habits from other sites where there is harsh censorship of non-advertiser-friendly language

Let's just get this out of the way...

Shit piss fuck cunt cocksucker motherfucker tits. And sometimes fart turd twat bitch.

Whatever is censored is being filtered by your instance.

Comes from the social media platforms that auto remove stories that contain certain words. Tiktok, Instagram, etc.

Some of them coughlemmy.mlcough has a swear filter

edit: world->ml

I've seen that for words that are considered to be 'triggers', as if saying 'r@pe' is somehow different at all than just using the normal vowel.

I have been watching Rick and Morty lately and every now and then I have to change the site to find a version of the episode I'm watching where swear words aren't censored. Like, it's a show made for adults full of violent and sexual themes, so I think that most viewers have heard the word "fuck" before. I hate it so much when people censor "bad words", even though nothing prevents them from saying them.

cause i'm f@cking polite you a$$hole!

One possible reason is that some words on controversial subjects can attract mobs of posters with an agenda. They search for keywords to find threads to flood with their arguments.

So posters would get in the habit of saying something like "I love p1n3apple on p*zza" to avoid the wrath of pizza purists (made-up example, but substitute with anything more controversial).

Habit. If I name my folder "Pron," then nobody who sees my desktop will know what's in it.

Because instances have language filters. On lemmy.ml you can't say "female dog", it shows as "removed"

I have noticed that my phone will autocorrect/misrecognize some swears. Fuck is often duck.

Because G-d forbids me from speaking or writing foul language.
