Subjective reputation system

Definition
Subjective reputation systems

"rely mainly on scores provided within a controlled community of users &mdash; where the community has well defined purposes, such as selling goods, sharing content, describing the experience of users, sharing knowledge or opinions. The community service provider plays a key role in running the reputation system, and both the provider and the reputation system have a reputation. Users rank "subjective" reputation scores for other community users, based on their personal interactions and/or the fulfilment of personal aspirations and promises/agreements, which may also vary in time. So, for example, one user may consider an e-mail interesting that others considered spam, and he can even change his mind in the course of the day."
