The same way websites like Glassdoor guarantee that the reviews posted on their websites are real. Hint: they don't :) A company's reputation isn't ruined by 1 or 2 nasty reviews (which will be deleted in a timely fashion should they be blatantly false). Statistically speaking the chances that someone would purposely make a bad story up to damage a company's reputation is negligible and so all of these "review" websites (and we) rely on a sort of "honor system", assuming that the majority of users will be honest. EDIT: replaced Yelp and Trip Advisor with Glassdoor (better example).
