I think it would be very difficult to detect these:
a) with 100% accuracy, and
b) without involving humans at all
but I noticed the trend of fake Amazon reviews some time ago, and some patterns were very evident. I'd click on the profile of a five-star reviewer, more often than not every review they left was five stars. And every product I'd click through on also had a deluge of suspicious five star reviews. I even started scraping data into a graph database but then discovered that Amazon tries very hard to resist scraping attempts and gave up.
I think it would be very possible to set up some kind of basic pattern analysis along these lines. Clearly, merchants are buying positive reviews in bulk, so detecting sudden spikes in positive reviews and working out correlations with other product review dumps wouldn't be difficult. Once you've got a sense of it, you hand the data over to human investigators who take it the rest of the way. But despite its insane wealth, Amazon is clearly not interested in spending the money required to do that.
