Why does google video search still allow scam users to show up as ‘SpaceX’ on YouTube? Doesn’t YouTube have a unique username system??

I assume a lack of manpower and lack of concerted attention to specific scams.

Another option is a Kafkaesque reporting mechanism in which a scammer took down their own videos before they could be reviewed by moderators. This is rarer but possible.
