Solicited?

Recently all of our positive reviews on yelp.com were filtered (hidden).  Their FAQs (I could not get a live person to discuss it with me) report that reviews are filtered if they are solicited. They say that they want to encourage objective reviews.
We encourage all our visitors to give us feedback on our web survey and through reviews.  We do not give discounts or incentives for reviews, but we do believe in the notion "If you like us, spread the word!" and if you did not have a good experience, please report it somewhere so that we can learn from it.
This same company is MORE than happy to SELL me options to increase my visibility, but casts aspersions on my asking my clients for feedback, implying that I am dishonest.  I am deeply offended by these implications made by a faceless entity who does not know me and I think it is an attempt to force me to BUY their ad service.  This is not how Applebrook Animal Hospital works and I feel that these practices are wrong!  I would encourage everyone to avoid this service and not be trapped into using it because it came pre-installed on iPhone and iPads. No one likes to be manipulated. 
Please continue to place reviews on our web site and anywhere you can.  I appreciate your opinions, no matter what. I am going to go back to being my positive and friendly self now...thank you for your patience! :)
