Ask HN: Are Scam Ads with Celebrity Deepfakes a Global Issue on YouTube?

Approximately 10-15% of the ads are scams. They feature Roger Federer or Swiss Federal Councillor Karin Keller-Sutter talking nonsense about quick money-making schemes (through poorly executed deepfakes). YouTube or Google doesn't seem to care. I can report the same ad many times, and yet, a few days later, it reappears.

Is this problem prevalent in other countries as well? Why isn't anyone taking action against it?
