No, name-calling is, but simple swear words are not. So just say it with me -
f
fuh
fuc
(you can do it!)
It has been my experience that “cunt” is currently our single most profane word in English, displacing fuck and various popular combinations like motherfucker and cockswallower.
You risk nothing so long as you don’t call names or post hate speech. Certain other behaviors can get you a warning, but they don’t revolve around the use of language.
In “Hot Fuzz” they had a sweat jar with penalty rates. All the words from 25p to £1. had a letter replaced by an asterisk as a nod to politeness, but cunt (£2.) was spelled out for comedic effect. I’m in enough touch with my inner12-year-old that I smile every time I see the scene.
