Iv seen posts with people substituting rape with r@pe. Other than bypassing filters I can’t see a reason to censor just 1 letter that doesn’t actually censor the word? I see if you fully censor the word, but even still context completely ruins the censorship.
It’s the same with most ways that we euphemise or censor words. It’s so pathetically redundant because everyone knows what the word is supposed.to be. You may as well have said it.
