I've also definitely sorted by date on Glassdoor and ignored any reviews that looked like they were posted all at once. On more than one occasion I've seen a blistering one star review, followed by a bunch of positive reviews that all came in within days. It was clearly a situation where someone at the company saw the low score, had an "uh-oh moment," and called in the cavalry to write positive reviews.
