The instance you’re on censors slurs. Mainly the b-word (misogynist term for women), but also the n-word (racial slur), various other lesser used racial slurs.

It does not censor general profanity like fuck, ass, shit.

Your only option is to open an account on another instance that doesn’t have as strict of a filter. Lemmy world for instance.

All content even from other instances is subject to this filter because it goes through your instance to get to you via federation.
