Karma whore
Karma is a scoring system on Slashdot meant to reward “good” posting and punish “bad” posting. The goal is that people who repeatedly post offensive, offtopic, or otherwise unwanted messages will be punished with a lower visibility of their messages, and those who post informative, insightful, or otherwise desirable messages are rewarded with a higher visibility. Karma whores are individuals, or messages themselves, that attempt to receive feedback in the form of karma points. Often these will be needless information (such as a link to a Wikipedia article relevant to the subject being discussed), or a message of a political nature that is in alignment with the groupthink so that it will be moderated upwards by people who agree with the stance expressed in the message.
