My recommendation engine told Silence of the Lambs readers to try Matilda
I built SageChimp partially because I got tired of not being able to tell if enthusiasm about a book was real. Separating unpaid reviews from incentivized ones, saying "not enough data yet" instead of inventing a consensus, that is the entire premise of the site. So, there is a certain justice in getting caught doing the exact thing I built the place to expose, in a system I had not thought to check.
