Still, the way they handle it is extremely bad. It takes a long time to get the account re-instated and they just take down the whole thing in the meantime. What they should do is make the account read-only and if it was taken over by a malicious actor then just rollback to a previous state asap. For accounts with millions of followers they should have emergency contacts and a process that resolves this within less than 24h. These Youtube channels generate serious revenue that easily would justify the costs.
