I would imagine any sort of product review classification system would be exploitable for abuse. Anecdotal evidence: when my mother and her team were running for student council (in college), the opposing team introduced blatantly fake votes (photocopied) in favor of her team; my mother's team got disqualified for cheating, and the opposing team won. So I could certainly picture a way in which a mischievous seller could submit fake-looking reviews for another product and get it taken down.
