Deplatforming

On YouTube the mechanism is channel termination, which can follow three Community Guidelines strikes inside a 90-day window, though one severe breach is enough on its own. The channel, the videos, the subscriber list and the AdSense relationship all go together.

The wider use of the word covers being dropped by payment processors, hosts and app stores at the same time, which is what makes it an existential risk for anyone whose entire business sits on one account. The defence is boring and it works: an email list you own, a second platform with a real audience on it, and local masters of everything you have ever published.
