This. Also, a couple of reviews won't sell your books. Twenty-five fake reviews won't sell your book. Many readers never ever glance at reviews. A good book, a good cover, good keywording, a good product description, and a number of books out in your name might start to sell your books if they are any good--but you need bookS, plural.
Reviews aren't very important. Period. Move on to what is important, getting your 5 or 10 books written, edited, proofread, and out there. Then you might see sales on book #1. Reviews do not change your visibility. 50 reviews at amazon does not make any magical thing happen to a book. It does not change ranking.
Look at my avatar. That's my daily sales at Zon midway through this past year. I never look at my reviews. I never think of my reviews or average rating or any of that. I do my job, which is writing. Reviews are not my job--and to write them for others in my genre would be against the TOS. As I make my living as a writer, being kicked off Amazon for violating TOS would be a very bad thing for me.
