Scammers promoting in the comments section! What to do?

Hi all. There is this scammer that has hundreds of Youtube accounts. He comments on really popular channels promoting a "book", and then uses his scam accounts to like the comment so that it's the first one on basically every video he comments on. The goal being that people Google the book and purchase it from his website. I assume he steals the credit card information and potentially has a virus included with the ebook someone would download. I've found him promoting on Joe Rogan, The Diary of a CEO, etc. Fortunately, YT allows you to see the last 3 comments left by users, which is how I find many of his scam comments and scam profiles. I leave a comment on each one I find letting people know this is a scam. My question is, how do I make YT aware of this guy? Is there anything that can be done? Below are some examples of the comments he leaves behind. "We are living in a trance. There is a reason they are trying to censore books like Health and Beauty Mastery." "How doesn't anyone know about a banned book Health and Beauty Mastery. Health industry is a big scam" "It's way more simple than you think. Forbidden Laws of Wealth by Victor Hayes revealed the hidden rules for real wealth-building. Successful people talked a lot about this book." Edit: not much response to this, but it's almost the ultimate scam. His comments don't violate YT rules, and pass the automated check when reported. He'll just keep getting millions of views to his websites for years to come. All he needs to do is keep his website up and running and 1 out of a million if not more will fall for his scam. It's a really smart scam tactic, I'll give him that. EDIT 2: the scammer is in the comments and is using the same tactic on Reddit now. I have screenshots of his comments and profile in case he deletes them.
