I'm not saying that they need to decay quickly, just that there should be some notion of decay on reviews. Reviews from last year are not as important as those from last week, especially for a food establishment. You're right though, there does have to be protections in place against gaming too.

The problem is though, that every company will get some 1-star reviews, and there has to be some mechanism for them to get erased (eventually). This mechanism should be open, clear, and well known, not $300/month to the rating company. Otherwise, once a long-running, good company gets some critical mass of negative/crazy customers leaving 1-star reviews, they'd have to close or rename or something in order to get back that unfairly lost traffic.
