The catfishing scam of self-publishing Kindle books with fake reviews

Someone once posted an article that asked why ebooks were becoming low quality. It is because of this scam apparently. Hiring a third world ghost writer that barely speaks English to write an ebook for $20, putting a pen name on it, charging $5 for the book and paying for fake 5 star reviews. Doing this with like 45 ebooks all of which are low quality, but ends up earning a lot of money in sales.

I've written ebooks on Kindle, and I don't make a lot of money from it. I use my own writing and I don't always get 5 star reviews, heck I'm lucky to get 3 star reviews. But at least I'm honest at it.
