You can't know them, when the council of awakeness performs the ritual of cancellation, the person is erased from existance, which includes everyone's memories, as if they never existed. Even the number of people who underwent this treatment is unknown, but we estimate trillions.
Several conspiracy lunatics got deplatformed. Trump literally got canceled off twitter, until his buddy Musk bought it back.
After #meToo and before his sentencing, I'm pretty sure Harvey Weinstein didn't do much movie producing either.
Influencers/personalities who don't get into illegal or seditious speech don't usually get deplatformed, so they have the option to stick around through heinous acts and subsequent harassment (e.g. the Paul brothers).
However canceling DOES work against people with, like, any semblance of humanity who can't wall off a continuous barrage of rape and death threats. Lindsay Ellis straight up closed up shop following a harassment campaign over some really stupid shit I can't even remember (she's back on Nebula now, but she's still off YouTube).
you can't say someone like trump got cancelled when he is like fighting for presidency of the largest military cult to ever exist or whatever he's up to these days.
If you want to establish cancel culture as a thing you have to
show that people can be barred from publicity and financial success
and
show that it is different from what happened in the past with reactions to scandals.
I just did. Lindsay Ellis got her carreer fucked by it.
Why? Just because the word changes doesn't mean the principle isn't still the same. And just because reactionaries like to call any mild backlash "cancelling" doesn't mean it isn't a thing.
