How is GlassDoor a protection racket? Are there any genuine complaints about them screwing over businesses? I once backed out of a job interview because of a slew of truly horrible reviews on Glassdoor. A bunch of current and former employees described a horrible work environment where the HR director, an "iron lady", seemed to run the place, with HR people in the parking lot logging what time employees came in, cameras in front of the bathrooms to see how long people were taking in there, etc. One bad review I'll generally ignore but this place was filled with a bunch of them; I'd never seen anything like it (and never have since).
