Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Fake reviews

Notice how all the reviews thus far look as though they've been written by the same person? And how none of the writers have any history of writing other reviews (even when they give their names, they're not underlined)? Please! You know the book must be really dreadful when publishers post fake reviews. Teach them that this isn't the way to sell a book... DON'T BUY IT!
