VOUCH

Summary from the TLDR newsletter

Vouch is a community trust management system. It requires people to be vouched for before they can interact with certain parts of a project. People can be explicitly denounced to block them from interacting with a project. The implementation can be used for any project on any code forge. Vouch lists can be configured to read other projects' lists of vouched or denounced users, so projects with shared values can share their trust decisions with each other.
