For both the recommend and don’t recommend situations, Fake reviews are longer. This can be that fake reviewers may need to achieve a certain length to gain the credits/benefits. Or, if we consider the very unsatified customers, they may create long fake reviews to express their anger.

If we compare across the recommand and don’t recommend, reviewers who recommended the product wrote shorter reviews. This may suggest that people who are satisfied with the product are likely to leave shorter comments like: “It is awesome! I recommend!”
