Mitigating Abuse

As we've noted at the end of Common Reputation Models, the incentive structures that reputation systems create and/or facilitate are often perceived differently that you intended by some users. There are often external incentives to abuse the reputation model to achieve an end of personal merit. For example, leader boards often lead to the creation of robots in an attempt by some to get the notoriety of being #1 on a large public site. Yelp.com banned the accounts of business owners who were writing positive reviews of other businesses using collusion techniques outlined in A Grammar for Reputation - direct profit is probably the strongest external motivator that drives undesired behavior. And that's before we even mention spam.

This sort of abuse mitigation is critical to the health of your reputation and proven techniques are detailed here.
