Glassdoor is all about transparency, so we take fraudulent activity very seriously, regardless of where it comes from.
To ensure the authenticity of the review content on our platform, we allow users to write one review per year, per company worked at. If a user updates a review within a year, the older review will be archived and the newer review will be listed. However, if we find evidence of a user posting multiple reviews for the same company through separate accounts, we will remove all contributions from that user's accounts.
Companies are also held to similar standards. While they might be tempted to offer employees special incentives in exchange for positive Glassdoor reviews, we have unique technology filters and algorithms to detect this type of fraud. (To protect our integrity, we don't share these processes.) If we learn that an employer has breached this rule, we will remove the reviews immediately.
We also rely on Glassdoor's active community to help monitor users. If you suspect a review of being fraudulent, we encourage you to flag it so that our Content Moderation team can take a closer look and remove it if necessary.
