How yelp can squander your customer’s goodwill.

One of my clients decided to register on Yelp and asked her customers to submit a review.  They took time out of their busy schedules, registered on Yelp (they never heard of it before) and submitted their opinions of her business.  The reviews are stored in the Yelp database, but are not showing up under her business because Yelp considers those reviews to be suspect.  She does not feel comfortable asking her customers to spend more time writing reviews on another site, so now she is left in a very difficult position.
