They don't even have to be that savvy. I worked for a company that got bought out and the new owners were terrible. The CEO was a friend of the owner, had no experience in the sector at all so he brought in consultants to tell us everything that was wrong with this profitable enterprise, the redundancies and cost-cutting started and people who had been there for years started jumping before they were pushed or just literally stopped working altogether and waited for their redundancy offer. The company started losing money, more cost cutting, that spiral. The Glassdoor reviews reflected all of this - generally positive until change of ownership, then a steep downhill. This was a while ago and I don't think the new management were even aware of Glassdoor to start off with, but somebody must have showed them because all of a sudden as soon as somebody posted what sounded like a very genuine negative review there would be a corresponding one that was just so glowing they were comical. This was around the time of the Trip Advisor scandal, after which they quietly dropped the "reviews you can trust" slogan. The two things have stuck in my mind together ever since.
