There's also the recent gofundme confiscation of Trucker Protest monies (those were eventually refunded but only because of all the publicity). And I wasn't arguing that it's happening on a large scale just that there is precedent and it's an obvious vector of attack the the Jewish bank cartel will use against dissidents more and more.

there are other types of work besides farming that do not depend on working at a megacorp.

I'm not advocating we all start farming. There are lots of potential alternatives markets that dissidents could get into to decouple themselves from large corporate and government control. Food is just a critical part of that decoupling and the farming community provides a unique oppurtunity for lots of other opportunities (religious worship, health/fitness, friendships, courtship, extended families, engineering, building, connection with nature. etc.)

Nick Fuentes and Laura Loomer also had trouble with account shenanigans.
