companies doding bad reviews means that companies with good reviews will stand out, making selection easier. as a consumer, i don't care about crappy products unless i end up purchasing them. i can avoid crappy products by only going for products with explicit positive reviews that i can trust. sure a grey area will continue to exist, but whitelisting is still effective for reviews, even if we can't blacklist.
