Luckily, it's pretty easy to spot fake reviews on Glassdoor. Unfortunately though, it kind of ruins the experience for most people.
The two big mobile app stores have been flooded with spam reviews for over 5 years now unchecked. For those that know how to spot fake reviews, it's easy to tell which apps are not legit. For most consumers though, they just believe what they see.
So... it's pretty easy to find reviews that you are confident are fake, and you're probably right about most of them.
But that only leaves us an uncorrupted signal if, given a review you have deemed authentic, it actually has a good chance of being so. Do you know that that's the case? How?
I'm not sure it's true in your case, but statements like this are often made when people don't realize they're (implicitly) marking their predictions against those same predictions.
Not OP, but how many times have I seen, under Management Feedback, "keep doing what you're doing!"? No, I don't mean paraphrased, I mean word-for-word. That's was a few years back, back when I thought Glassdoor was worth paying attention to. I'm sure whatever HR conference they all communally go to has new guidance for gaming reviews, and the phrase has changed since.
