I tried to review Dr. Corsi's new book today on Amazon. Here is the message I got:

Sorry, we are unable to accept your review of this product.

Amazon does not permit reviews from customers whose relationship to the product or seller may be perceived as biased.

I purchased the book from Amazon where I have had a Prime membership for over 10 years. I don't even know Dr. Corsi and have never spoken with him. I guess I've been blacklisted.
