This is not a single event. It is a pattern that took me some time to recognize after shopping with Lazada several times. The reviews on Lazada are fake in the way that bad reviews are removed. Additionally fake products are sold there, but if this is ever mentioned in a review, it will never be approved. I am guessing that operators that work with Lazada take a bribe from their customers (that are different small shops selling different items) every time there is a review that they do not like. Twice I have been scammed on this page and both time the reviews are magically gone.
The first time was an instance where I bought Legend RAM. It did not occur to me that it could be fake until I was about to put it into my mac. I sat down for an hour and checked serial number and other signs of counterfeit product, and after the check it was pretty obvious that it was fake. I wrote a moderately opinioned review where I mentioned that I was disappointed because it was fake. Needless to say, this review never saw the light of day. However, there are a few negative reviews that they tend to keep in order to make it believable. After all, who would believe if you have 1000 reviews and only 5 stars. Instead, they have a couple of bad comments, but they make sure that it is not something too negative.
