What you’re describing is a popular scam where a scammer rebroadcasts a previously run live stream with famous people and instructions to send crypto to an address for a “giveaway”. Since the livestreams are about crypto, people tune in and see a banner saying “send crypto here for a chance to win more crypto”, see a conversation that seems live with people they know, and fall for the scam.

These people you mentioned are not actually doing a giveaway, and YouTube is completely asleep at the wheel for combating these sorts of scams (they’ve been around for a couple years now, and automated detection is a harder engineering problem than scraping tweets).

The problem is that they’ve very lucrative for scammers since the scam is confusing enough for people that they think they’re credible, doubly so when they use hacked channels with changed names but have hundreds of thousands of followers to do the broadcast.

IMO YouTube absolutely needs to step up their game here - I’ve fought this sort of fraud at larger orgs and Twitter and Facebook both have pipelines established for security teams to escalate these things, meanwhile YouTube takes a report, let’s the scam run to its entirety, then picks up the pieces after the damage has already been done.
