Regardless of what their claims might be, Yelp does indeed remove low ratings and poor reviews at the request of business owners and managers, most notably ones who advertise with them. One of the sleazy ways around admitting to this is placing a poor review into the reviews "not recommended by yelp" area, hoping you wont read them. They will throw an occasional 4 or 5 star review into the mix to make it look like its all on the up and up, but it is not. After watching several local businesses in the area for some time its almost comical to watch the negative review on them disappear in a short period of time, with yelp hiding behind the pretense of this process being "automated". Be careful when choosing a place to eat or shop when using yelp, you can easily get burned by false positive reviews and deleted or hidden truthful reviews. Always double check with sites like tripadvisor and other review sites, where they do not cater to businesses for their own personal gain. Any business who advertises with Yelp can have your negative reviews deleted immediately, no questions asked. These guys are bought and paid for by some of the shadiest businesses in the entire world. 1 star is much to high for this pathetic, extremely dishonest app that is Yelp. Not to be trusted. Patronizing any of the businesses who advertise with them is extremely risky.
