In my experience, it's far easier and more common for companies to simply flood their review pool with bogus positive reviews, rather than bother about negative reviews. Plenty of startup founders boosted their rating by telling HR, family, friends, and foreign clickfarms to post 5 star Glassdoor reviews. It's extremely easy to inflate your rating this way. Glassdoor does nothing to prevent it. There are small startups with more 5-star Glassdoor reviews than employees. As long as your bots also upvote every other 5-star reviews, anyone looking at your review pool, sorted either by recency or "most helpful", will have to scroll through dozens of these bogus 5-star reviews before they get to any real negative review. By that point, the negative review will seem like a biased exception posted by a disgruntled employee - if they even get to it. The worst aspect of this is how easy it is for truly terrible companies to royally screw their employees yet retain an eye-popping 4.2+ rating on Glassdoor. I've seen a couple of cases where companies badly mistreated employees, got a well-deserved torrent of 1-2 star reviews as a result, then flooded their pool with hundreds of fake 5-star reviews. Now these terrible companies, that truly do mistreat and abuse their workforce, have a Glassdoor page and review pool disguising them as a top 1% employer.
