It was a very boneheaded move by Amazon and a classic example of the controls being worse than what you're trying to protect against.

Having friends and family giving glowing reviews of books is mildly annoying (although expected). Having a company respond by in essence saying, "We removed your review, big brother is watching, you're a liar, we know because we're prying into your personal relationships but we won't tell you how we know because that's personal (I mean proprietary). We're going to ignore you now." Well that's much worse.
Bad PR move by Amazon.
