I could envision someone setting up forums on the darkweb to discuss the pros and cons of companies to mitigate some attribution but I do not see how anyone could make money unless they play ball with the big companies which renders the site pointless much like glassdoor as become. The money made would be from bribes from shady companies and then bigger companies might take the money away. Prior to GD was f'd company and I don't remember why they went away.
