As documented by NeoGAF through a series of images (one of which was timeposted at 01:09 AM London time and is posted above), Amazon has been removing negative one-star and two-star reviews for Titanfall. Perhaps they are doing it of their own volition, or perhaps out of pressure from outside forces; either way, the customer reviews had risen to an average of 4.5 stars.
There was a chance that this removal was done to restrict the number of trolling reviews, but some of the nixed reviews were from legitimate verified purchasers. This thread on the customer discussions forum has multiple reports of people who purchased Titanfall through Amazon, reviewed it low on Amazon, and then had their reviews promptly removed. The top comment from James reads as follows:
I did not like Titanfall but I did buy it here on Amazon. I know many people disagree with me and thats fine. We can debate on things I did not like. But it should concern us all that people that have the "verified purchaser" label are being removed with other people that did not purchase it or is an obvious fanboy.I always thought that even if a review of anything was bad the " verified purchaser" meant they at least bought it. It gave there review more legitimacy. If its fair game to remove peoples reviews like that its un-ethical.
But now I will need to not consider reviews at all on Amazon as its safe to assume reviews have been removed so they can sell more of something.
Luckily (and unluckily for others), Amazon has since restored many of the reviews, with the average score now sitting at 3.5 stars. But this doesn't bode well for future video games being sold on Amazon, setting a dangerous precedent for user score fixing.
