Jeff Bezos and company gave Berenson a suggestion on how to adjust his approach: "Please consider removing references to COVID-19 for this book."

Berenson's book, titled Unreported Truths About COVID-19 And Lockdowns Part 1: Introductions and Death Counts and Estimates, was to be the first in a series of short e-books about the coronavirus. The author planned to publish via Amazons' Kindle Direct service, which allows authors to self-publish electronic books.

But Amazon said no. In an email from Amazon that the author published on Twitter, the online retail giant informed the author that the book "does not comply with our guidelines," and that Amazon customers are being referred to "official sources" about the virus.

"Due to the rapidly changing nature of information around the COVID-19 virus, we are referring customers to official sources for health information about the virus. Please consider removing references to COVID-19 for this book."
