Amazon has said it blames social media for failing to react quick enough to stop groups set up to organise and perpetuate fake reviews.

There's no doubt these fake review are a real pain, but i'm now considerably more wary when reading the reviews and accepting them as being accurate. I was caught out quite a few years back. Having dug around the product reviews I realised that when someone put up an objective review, it was rapidly followed by a few five-star, fantastic product reviews, pushing down the real reviews. I tested it myself (the product really was a waste of the world's resources) and put up a factual review. Within a couple of hours, miraculously, several glowing reviews pushed my truthful review off the new reviews.
One bitten, twice shy.
Amazon needs to get a grip.
