Mecha-Streisand, during pectoral venting.
In a surprisingly unbiased article, given the source, USA Today reported that Amazon was removing most 1-star reviews of what I'm sure is Hillary Clinton's magnum opus of blame-shifting^: "What Happened".
The hilarious part is Amazon's public response, which according to USA Today, seems to have been delivered with a straight face in a truly herculean task of cognitive dissonance.
"It’s not our role to decide what a customer would view as helpful or unhelpful in making their decision."
Remember, you have to read between the lines. They mean "unless by pushing an agenda we can either make more money or place our most thoroughly purchased politicians closer to legislation that will make us more money later."
I'm not sure which one of these is in effect here, or whether someone is simply calling in a favor or can't bear to turn on a losing team, but regardless of the motivation it's an odd choice at a time when Amazon is generally looking pretty clean compared to the likes of Google or Wal-Mart.
As usual, her human behavior replication program appears to need some rejiggering.
Despite these lame cover-ups reliably backfiring in the era of internet archiving, they continue to be attempted. At least pre-wide-internet adoption, maybe you could concoct some sort of amoral, game-theory argument for attempting a cover-up.
However, simply deleting reviews until the actual displayed ratings are completely incongruous with the actual reviews users will see on the product page...that's simply self defeating. Let's take a look at how this is going for Amazon, live, a few days after this story actually broke:
Predictable Streisand-effect: achieved.
Those reviews don't even sound biased, they just sound bored and disappointed.
Honestly, it couldn't happen to a better totally-not-a-non-human than Hillary Clinton.
This author might humbly recommend that Mrs. Clinton takes solace in an open and honest community that will not only sympathize, but empathize, with the long struggles of her career.
Good place to start.
