Abstract

Embodiments are directed towards generating a unified user account trustworthiness system through user account trust worthiness scores. A trusted group of user accounts may be identified for a given action by grouping a plurality of user accounts into tiers based on a trustworthiness score of each user account for the given action. The tiers and/or trustwor thiness scores may be employed to classify an item, Such as a message as spam or non-spam, based on input from the user accounts. The trustworthiness scores may also be employed to determine if a user account is a robot account or a human account. The trusted group for a given action may dynamically evolve over time by regrouping the user accounts based on modified trustworthiness scores. A trust worthiness score of an individual user account may be modified based on input received from the individual user account and input from other user accounts.
