> "Blind allows employees at companies to share their opinion anonymously, which means they can share their honest opinions without fear of judgment," as Kyum Kim puts it. Furthermore, Blind users can only join its Blizzard community if they create an account through their company e-mail.

Those two statements are at odds. Any large company (especially in a technical industry) is going to monitor internet usage and retain e-mail/internet logs, or at least have the capability to do so. Anyone with a technical background is going to understand that using their employer's infrastructure to verify is going to directly link their real/work identity with their Blind account. Even if you were to trust that Blind would not provide their information to 3rd parties you would still have to assume that the company could still easily find out who had answered questions (but maybe not how they answered). Depending on how the publicly reported results were skewed, and how many people responded, that could still very easily lead to someone being directly identified or at least flagged by their employer.
