| Surely a simple solution here is for Glassdoor to show removed reviews with a simple placeholder text and a reason for removal. Glassdoor could also account for these in its overall rankings, and show a graph plotting number of removals against time. That way companies legitimately removing invalid reviews can continue to do so, but those gaming the system would have that activity show up. If they plotted submitted reviews as well you could see when these periods of mass removals and "forced" positive reviews happened. Glassdoor could also provide a short summary of "X reviews removed in the last Y days - this is lower/higher/inline with the average". All of this is easily within the power of Glassdoor to do and keeps the platform fair for both parties. |
Maybe it sounds cynical, but that is the business model.
