Self-censoring swearing and serious topics will never not be ridiculous to me. I especially dislike the trend if censoring them by replacing letters with numbers/symbols, because I don't see that well...
I'm fine with self-censorship so long as it's also self-aware and funny, llike that D&D group on youtube where they replace penis with "schmenis", that outright elevates things.
Ideally take the opportunity to be creative with euphemisms, blur the line between censorship and art.
