Glassdoor is owned by a Japanese co (Recruit Holdings) - I have firsthand knowledge that user/poster data is not safe - Manager Glassdoor Employee Review

We take this type of allegation very seriously. The privacy of our users and their information is of critical importance to us. Your claim goes against everything Glassdoor and our parent company, Recruit Holdings, stand for. Protecting the privacy and anonymity of our users and maintaining their trust are paramount to our missions and integral to how we operate. Although we have strong reason to doubt the accuracy of this claim, we are very carefully reviewing your allegation while strictly following our internal processes which protect user privacy. I encourage you to contact me or, if you prefer, our internal employee whistleblower hotline and share any further information anonymously without fear of retaliation or retribution. I want to emphasize that the integrity of our content moderation policies is at the core of who we are. Glassdoor has always been and remains subject to the very same content moderation policies as all other employers. So much so that only a very small subset of our content moderators have the ability to see who submits reviews about Glassdoor. And our policy is strict: nobody, least of all a senior executive at Glassdoor or Recruit Holdings, is permitted to obtain user information in the way described or about anyone who shares content on Glassdoor. Again, as a matter of policy, all reviews published on Glassdoor must be in alignment with our Community Guidelines and Terms of Use. The same standard applies to Glassdoor that is applied to all employers. Christian Sutherland-Wong, CEO
