The BBC have posted an interesting article about the problems on spam reviews that are a cause for concern not just for the consumer but for the manufactures. When it comes to buying products over the Internet we all tend to view the reviews from people who have brought the product.
The problem is now that many reviews now are fake reviews either paid by the competitor or caused by people spamming a certain product based in popularity / ehnical status. Apple anyone?
