If you suspect a competitor is posting false reviews of your business the first thing you should do is contact the company where the review is posted and raise your concerns, here is an example exchange that resulted in the competitors negative and false review being removed
[Delicious Webdesign] Had a review from John Wood on the 11 Oct 2011 from Email Address lkk776@hotmail.co.uk, this is not someone we have had as a client or as someone that has attempted to contact us and his comments are malicious and false, please can you remove this review. In response the the review saying we have low quality websites please see the first page of our portfolio and the second page of our client comments and can re-confirm I have never had an email or phone call from this person and they are not a client but suspect its a Website Design competitor in Stanford-le-Hope
