Citysearch City Grid Fake reviews show up when you don't advertise. Internet

I am a business owner who doesn't advertise with City Search and a fake bad review shows up while great reviews mysteriously disappear. How do these fraudulent companies allowed to scam small business owners? Yelp is also another scammer. We all must report these scams to FTC and BBB. If you refuse to advertise on City Search, wretched reviews mysteriously and suddenly appear on your profile page en masse. I recently had to deal with Yelp's scam and now CitySearch is doing the same. HELP! Why are these Internet mafias allowed to steal from small business owners? It's hard enough trying to run a business and have to also deal with these bad companies putting out fake review to destroy your business if you don't advertise with them!
