Well, I was not going to reply to this, but since I just watched
South Park, and had a few beers... I cannot help it.
Amos.... get a life buddy -- you are loosing control. If you publish anything that is "false" about a person you are not protected by any "editorial" law. It's called "defamation." A review is no excuse -- especially now that you have threatened to do so in a public forum.
This is true, although having spent a sliver of time studying first amendment law for various journalism classes*, I can say pretty confidently that it is highly unlikely that Amos could say something actionable in the review of a book. For one thing, he's only commenting on what someone else wrote. If anything would be actionable, it would be the original book that he's commenting on, unless he makes libelous allegations that extend outside the umbra of what the book suggests. He'd have to be way further over the line that you're imagining for it to be even worth a cursory glance from an attorney. In fact, it would seem that Warren has gone out of his way to make himself a public figure. One you're a public figure, there's not much at all that one can't say or print about you and get away with it. You literally have to prove that someone knew something was false and then maliciously printed it to intentionally defame your client, and then you have to show tangible evidence that your client has been somehow fiscally harmed by the statement. That's way harder than that even sounds.
So, while waving cartooney lawyer threats around may make you feel better about the whole thing, it doesn't mean very much in terms of legal reality. You may stifle the comments of people who aren't experienced with publishing or law or whatever, but in case you didn't notice, Amos doesn't seem to fall into that category. You're probably more than welcome to sue Amos for whatever he writes, but it'd be a waste of your time and money, and I daresay it'd make you a bit of a pariah around here. I'd stick to watching Southpark, were I you.**
For what it's worth, likely the book publishers would have no ammo at all to sue Warren, even if it were to be shown that he somehow convinced people to write negative reviews on Amazon. AFAIK, there's nothing illegal about writing lots of bad reviews for a book.
