Rick Beato had an episode about AI music where he talked about how easy it is to game the iTunes charts. So few people buy music from iTunes that it's relatively cheap to buy your way onto the charts.

I saw a video of guy who became an Amazon bestseller in a book category pretty easily by buying his own book.

Through my professional / personal network, I know someone who advertises himself as being a “Best Selling Amazon Author in XYZ category.”

It is semi niche, but I did some ballpark math, and about 72 sales rapidly would put him in the top spot for that niche.

That number sounds about right when he’s mentioned the gross $ sales of his book.

Pretty common for authors to get people to pre-order their books so when they go on sale they top the chart for that day (the book's release day) in their category.

Not even just for their category. "NYT bestsellers" has been manipulated like this since inception.

NYT bestsellers is also not a sales volume chart, there is an editorial lens to it as well
