Yelp is a leech on every small business owner in the USA. Their strong-arm tactics leave defined winners and losers. I've watched yelp drive business owners to madness. I've battled rogure reviewers leaving false reviews. My business page will absolutely deny every single review positive review left on it because Yelp wants to strong arm me.
And against all their guidelines I've witnessed a review from a person with 1 review, 0 friends, and a fake alias sit on a page for 8 months, it read something like "I called and they told me they did not perform the service I wanted and hung up. 1/5 stars."
Fuck this evil company.
