I saw something similar being claimed by Yelp in one of their promotional videos. https://www.youtube.com/watch?v=jbkQtW8A408 And after watching it had the same doubts that I have now:
Aren't most paid reviews done by agencies which have either 1) An army of employees who have old profiles with several reviews and are trained to give a balanced review? Why is their writing style likely to be any different from real reviewers? There is a high probability of false negatives. This might just weed out the bad freelancers who put no thought in writing such reviews.
Or 2) They will pay real reviewers who are influencers to give them favourable reviews. And these you cannot and should not remove in any case.
Also, What check do you have against false positives?

And what do you think of solutions which rely and actual verified human intelligence? Like: http://www.inc.com/magazine/201404/liz-welch/stella-service-...
