These days more and more books are bought, sold, and recommended on-line, and the health of this exciting new ecosystem depends entirely on free and honest conversation among readers. But some writers are misusing these new channels in ways that are fraudulent and damaging to publishing at large. British author Stephen Leather recently admitted that he used fake identities online to promote his work. The American bestseller John Locke has revealed he has paid for reviews of his books. The British author RJ Ellory has now confessed to posting flattering reviews of his own work and to using assumed names to attack other authors perceived to be his rivals.

These are just three cases of abuse we know about. Few in publishing believe they are unique. It is likely that other authors are pursuing these underhand tactics as well.

We the undersigned unreservedly condemn this behaviour, and commit never to use such tactics.

But the only lasting solution is for readers to take possession of the process. The internet belongs to us all. Your honest and heartfelt reviews, good or bad, enthusiastic or disapproving,­ can drown out the phoney voices, and the underhanded tactics will be marginalized to the point of irrelevance. No single author,­ however devious,­ can compete with the whole community. Will you use your voice to help us clean up this mess?
