It’s not children censoring things. It’s people obfuscating words that may get flagged and have their post removed.

These days software can scan images and videos and not just text, for violations of whatever rules they have.

Like on most of the mainstream platforms just the audible mention of suicide gets you flagged. So people have adopted ways to avoid detection like saying unalive instead of suicide.

This censoring of the word death is not for ethical reasons as you are insinuating.

Basically don’t let it piss you off. Terrible hill to die on.
