Maybe you’re right: is there verification?

Neither content policy (youtube or tiktok) clearly lays out rules on those words. I only find unverified claims: some write it started at YouTube, others claim TikTok. They claim YouTube demonetizes & TikTok shadowbans. They generally agree content restrictions by these platforms led to the propagation of circumspect shit like unalive & SA.

TikTok policy outlines their moderation methods, which include removal and ineligibility to the for you feed. Given their policy on self-harm & automated removal of potential violations, their policy is to effectively & recklessly censor such language.

Generally, censorship is suppression of expression. Censorship doesn’t exclusively mean content removal, though they’re doing that, too. (Digression: revisionism & whitewashing are forms of censorship.)

Regardless of how they censor or induce self-censorship, they’re chilling inoffensive language pointlessly. While as private entities they are free to moderate as they please, it’s unnecessary & the effect is an obnoxious affront on self-expression that’s contorting language for the sake of avoid idiotic restrictions.
