So this dude offers a free autographed hardcover paperback of a *different* book if you will post a review on 'zon and GR and pm him.
And really doesn't see any issue with that (but did write a nice snarky post quoting lots of govt websites at me). Link in spoiler below, if you wanna read the exchange.
I've had this argument before with authors, and I don't understand why they can't see the difference between providing a product for review, and providing a prize as an incentive. It's not that hard is it?
Oh well, another author I won't be reading.
