Stop Yelp.com from destroying small Businesses

Yelp.com is destroying small business in America by publishing inaccurate customer reviews on their website.
Consumers view these reviews as reliable source of information and can base their decision on them.
More often then not, yelp reviews are inaccurate. This has been experienced by numerous small businesses. The company hide behind a 'review filter' which supposedly filter fake reviews. In reality, the positive reviews are unfairly filtered but the negative reviews stay. The small businesses are pressed very hard to buy marketing by yelp.com. This can severely hurt small businesses which depend upon recommendations from their customers.
Online review industry must be regulated by the government. I would urge President Obama to prevent one company determine fate of small businesses.
