Just today I was trying to find some earphones on amazon and came across following seller page. https://www.amazon.ca/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=MXditect https://www.amazon.ca/s/ref=nb_sb_noss?url=search-alias%3Dap... Almost all of their products have 500-600 reviews and all are 5 star, not even a single one is less than 5 stars. Moreover, most of reviews are created in November 2017 and each reviewer has left couple of 5-star reviews only for same seller's product within a week. These fake reviews could have been detected by even a basic detection system. Not sure why Amazon has not already detected and removed them.
