It may be to bypass censorship, rather than self-censorship. Some platforms block or shadowban comments with curse words. Not sure about this platform.
I do find it a little amusing, because commenters stopped criticizing my cursing the moment I started getting a good chunk of karma here. I remember in 2016 someone criticized me for using the term "shitposting"...I don't think I've gotten that kind of criticism since 2016 though.
