Of course, it's a useful service, but once you're in among the weeds, questions begin to be raised. Most recently, I added a review about an online seller. I explained why I didn't buy from them after I reached the checkout because what was advertised as a FREE DELIVERY service was in fact anything but. Rather than responding to my review the seller complained to Trustpilot and had my review removed. The reasoning given by Trustpilot was I hadn't actually had "a customer experience". This seems like a nonsense to me. I never claimed to have bought anything. In fact the whole point of my review was to explain why I my limited "customer experience" led me to choose not to buy. Trustpilot's stance is that you need to be willing to enter knowingly into a bad "customer experience" before you earn the right to alert others to it on their website: take a bullet or move over. For me it raises the question of what other collusion exists between sellers and Trustpilot. This experience significantly impacts on the credibility of the website for me. At some stage it will stretch beyond breaking point.
