Amazon halts tit-for-tat critics
Charles Davis writes "Authors and publishers face credit card barrier to anonymously puffing their books.
The world's biggest online bookseller, Amazon, is to clamp down on anonymous reviews of titles on its website in an attempt to curb excesses of back-stabbing in the competitive world of publishing.
After mounting concern about abuse of its open door policy regarding feedback, Amazon has begun a new system, Real Names, which requires reviewers to provide their credit card details before posting a comment.
The change, which was quietly introduced earlier this month, is intended to put an end to authors and publishers anonymously showering their own books with praise while trashing the work of their rivals. An Amazon spokeswoman said: "This is the latest step in an ongoing effort to continually improve the content of the site."
