Youtube has had a scam video ad up for 3 days now advertising fallguys for mobile where it's just a page that forces you to install other apps. It was blatant and I reported it but YouTube can't be bothered to dispatch a human to look at it. I've seen more promoted Livestream scams in the last 6 months promising crypto giveaways than ever. They're equally blatant and impersonating tesla, spaceX and even Steve Wozniak…
That's the same thing with copyright scams and counterfeits on Kickstarter and co, Kickstarter doesn't give a flying "fork" about user reports until Disney or Sony send their lawyers.
I also remember that blatant Youtube live bitcoin scam just after the Playstation 5 reveal which Youtube let run despite perhaps thousands of user reports. Youtube could not NOT know this scam was happening.
