It's disgusting and rather scary that a private company can take action like this against a man who has not been convicted of a crime and whose behaviour on their site has apparently not breached their rules. You Tube has no business policing anything in the real world and their treatment of Brand is an abuse of power analogous to the way that that other repulsive creature, Farage was treated by Coutt's.
That said, a million a year seems a lot to lose. I hope the repellent arsehole is crossy-wossy.
