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.
So I think “kill” is fine for the Tiktok censors as it can be used in various contacts that don’t necessarily mean death. Murder, suicide, and rape are definitely words that will get your content or comments removed, hence “grape” (or r@pe), “unalived”. Which is a bit frustrating when educational creators can’t actually talk about their specialist subjects but oh well.
