Nothing goes live on its own
Every company, brand, product, review and owner reply is submitted unpublished and stays that way until an administrator approves it. That applies to the first version and to every later one: editing an approved listing returns it to the queue, so a page cannot be changed into something different after it was checked.
We do not publish a listing and moderate it afterwards. The trade is that approval takes time; the benefit is that nothing reaches a reader unread.
