Anonymity by Design
Glassdoor is built around anonymous employee and former-employee reviews, which is central to its value proposition and makes identifying a reviewer considerably harder than on platforms tied to real identities. That doesn't make a false Glassdoor review unaddressable, but it does mean the investigation typically focuses more on the content itself — whether specific factual claims are verifiably false — than on identifying the author.

That includes documenting specific factual claims within a review (as opposed to opinion-based statements, which are typically protected), cross-referencing claims against employment and HR records where available to counsel, and preparing a flagging submission under Glassdoor's community guidelines.
