This sounds like a system that is no longer valuable for it's original intended use case. I am just thinking out loud, but maybe one feasible response would be for people to create their own anonymous blogs about their experience at a company. I consider that a more distributed approach that may be more difficult for companies to game. If I were to create such a blog, I might use a disposable email address and create a blog on something like neocities [1] and other free static web site providers. Perhaps some of these sites would even allow access via Tor or other proxies. Can you think of any other mediums that may be useful for this purpose?
