According to Chow's posting policy, "Posts alleging food poisoning and other restaurant health-code violations (like finding bugs or other foreign objects in your food) are not permitted. An online discussion forum is not the place to report urgent and serious public health concerns. If you notice something, please tell the authorities."
This makes sense - it's just one diner's experience, possibly false, possibly part of a vendetta. But what does NOT make sense (but is happening right now) is to prevent people from discussing that a restaurant has been cited for violations. That's not an allegation. It's a fact.
