body: My mate was buying a car from AutoTrader UK and heavily relying on reviews in their website. When I mentioned it to a relative of mine who owns a car supermarket he said that to post a review in AutoTrader you need to contact the dealer and ask them for a link. This obviously means only good reviews would go online unless someone is shameless and determined to post a negative review.
  
  
  Slightly related to [this question](https://law.stackexchange.com/questions/7688/is-it-legal-to-publish-a-review-of-a-travel-service-without-letting-the-service), but still different- is it OK for a website to only post positive reviews for their sellers?
