I think we have all come across some anonymous reviewers who seem to over the top with their reviews. The problem is that today many of us read reviews from unknown people to decide what books to read, what movies to see, where we stay on holidays and what resturants to try.

There is a good chance that many of these glowing or disarster reviews aren't authentic. Today many offer to write such reviews for marketing. Here are some that I pulled out of one such site, fiverr where people advertise their services for such things.

Here are some samples of people offering their services at fiverr for Amazon.

• I'm a professional writer, specialize in reviews, interviews, press releases, essays, books, articles, etc. I will write you a great 5 star review for your book, movie, amazon product and post the review on bn.com, amazon.com or the website of your choice. ....

• ....The more links that lead to your product, means more ways for people to find & buy your book. I will create 3 listmania lists with your book at the top of each list. For example, if you are selling a golf book, I will create a list for my favorite Golfing books, and yours will be highlighted at the top. 3 separate accounts all adding your book link to Amazon.

• I will review up to TWO different products. I will give a 5-star positive review for your kindle, book or whatever product you have on Amazon. .... My reviews will be tailored to match your product and will have a "genuine" feel to it and not appear spammy, such "cool book" or "nifty product, go and buy one" etc

If you see some suspicious reviews, this may help you, reviewskeptic Some of the travel websites are already starting to add this technology, although from what I understand not TripAdvisor. I look forward to a firefox add-on incorporating such technology, although I suspect that we are about to enter a battle between the writers of such reviews and the developers of this technology.
