2. Put together a list of recent apps reviewed by a certain reviewer, then examine other reviews for the same application. If you notice a pattern among these reviewers, they all are likely paid reviewers.

3. Count the number of words that have been written. Fake reviews are often less than 5 words long and overly simplistic.

4. When a review contains too many keywords, we can deem it as bogus.
