Glassdoor is a web site where workers rate their current or former employers. Like all online review web sites, the ratings have become flooded with fake reviews, in this case, orchestrated by employers.

Online reviews – of all types – have become near useless. TripAdvisor was previously caught censoring negative reviews. Amazon reviews are flooded with fake and paid reviews.
