I personally saw the reaction within Zillow Group when Spencer Rascoff got a bad rating on Glassdoor. The reviewer was located, the review was quickly deleted, and Spencer's rating continues to be a source of pride for him.
Don't get me wrong. He's extremely capable and will probably continue to run ZG very well for years to come. But his Glassdoor rating should be lower and it irks me every time I hear it touted.
