Some indie author on Amazon apparently snagged a bunch of email addresses from Kindleboards and sent random people emails pimping her book. This is not a good way to make yourself popular with readers, and it's particularly likely to backfire on Amazon, where people are fairly cranky about spammers. Already she's gotten three bad reviews out of it. There are ways to promote your indie book, but this isn't one of them. Stuff like this doesn't do the rest of us any favors, either... it just gets readers' backs up about ALL indie authors, even those of us who are professional and courteous on the boards.
