Controversial users

From TrustLet, a free, collaborative project for collecting and analyzing information about trust metrics.

Controversial users are users who are trusted by many other users and distrusted by many other users. They attract different judgements (trust statement) from different users. Note that every trust statement is equally worth since trust is subjective and so it is not reasonable to assume some users are right and some other users are wrong, simply they hold different subjective opinions.

A paper analyzing the topic is Trust metrics on controversial users: balancing between tyranny of the majority and echo chambers. For example if a user A in a network is trusted by 5 people and distrusted by 5 people the user is said to be highly controversial. In this paper, two quantities are defined: controversiality level and controversiality percentage.
