I have always wondered why YELP and Amazon Reviews and other review sites work as well as they do since a company COULD flood one with false reviews (high marks for their company or low marks for their competitors). From what I've seen this does not seem to be a big problem.
Even so, it is A problem, and amazon is taking action on it. See here for details.
A while back I posted a review that is... not sure its false, but I am surprised they allowed it and still allow it. What happened: I bought a copy of my own book Bounded Queries in Recursion Theory (Gasarch and Martin) since my dept wanted a copy to put in one of those glass cases of faculty books. I bought it used for about $10.00. I got email from amazon asking if I wanted to review it, so I thought YES, I'll review my book! I wrote:
This is a great book. I should know, I wrote it.
I am surprised Amazon ASKED me for my opinion.
Seriously- I also have a survey which says whats in the book
better, email me if you want it, firstname.lastname@example.org
That was in November of 2014. Its still posted. Is it a false review? Not clear since everything I say in it is true and I am honestly saying who I am.
If Amazon removed it I would be surprised they noticed.
If Amazon does not remove it I'm surprised they allow it.
Is it possible to be surprised both ways?
