I was expecting a big, tearful "OMG I did it and I am sad, forgive me" or something, but actually, there was nobody confessing to anything. It was a story about how a fake reviewer was found out, no more.
The reviewer's techniques aren't even particularly interesting. It's no surprise that she (presumably) was caught out, since anyone could have verified that bias with a quick glance. I'm more interested in learning about people who do this for profit, how many of them there really are, and how they manage to stay hidden.
