Where did my CC site review go?

I recently wrote a review of a site that I spent several nights on.  I made some negative comments - nothing terrible but I thought they needed making.  I had booked onto that site on the strength of the reviews.  I felt that they did not accurately convey some very important issues of safety and cleanliness.  I checked to see where my review was.  Nowhere to be seen!  Has anyone else known their review to go AWOL?
