That makes sense. Employers save themselves a lot of employee dissatisfaction through honesty and transparency during the hiring process. If they misrepresent themselves, they end up with employees who aren't a good match as a result of decisions made on bad information, and who feel cheated to boot.

Edit: Some companies misrepresent their cultures because they know their actual behavior is unattractive to workers. Bolstering Glassdoor reviews by encouraging unusually satisfied (or otherwise motivated) employees is just another form of this. The strategy is successful at tricking employees into accepting poor working conditions while also demonstrating that the employer isn't worth trusting.
