Cancel culture should be renamed "disfellowshipping culture."
When a Jehovah's Witness commits a bad enough sin, or worse, questions church doctrine the congregation disfellowships them. That means they're no longer allowed to participate in the congregation and no other Jehovah's Witness is allowed to speak to them. Including their own families.
If a JW does speak to them they are also disfellowshipped. Same thing happens if they disagree with the church's decision or failed to report that sin before someone else.
However, if a disfellowshiped person waits a while and makes a convincing apology they can be reinstated. The system is based more on politics and personal appeal then what they actually did.
IMO, this is a good metaphor for modern social media bubbles.
