This comment reminds me of the days when I had to run mail systems and people would complain about receiving spam. Doesn't matter if you block 100 spam emails from their mailbox, if even one gets through, the spam filtering is crap. Especially if the spam is "obviously spam" to their human eyes. Amazon might very well be filtering out a massive amount of fake reviews. In fact, they might be filtering out the vast vast majority of them. But because you can see still see a lot, they must be "unwilling" to do it.
